  1. CVE-2026-114406 6.8 Moyenne

    Red Hat Hardened Images · Red Hat Assisted Installer for Red Hat OpenShift Container Platform 2 · Red Hat cert-manager Operator for Red Hat OpenShift · Red Hat Confidential Compute Attestation

    The system certificate authority (CA) store in Red Hat products, distributed via ca-certificates RPM packages, included multiple root CA certificates of authorities, which signed intermediate CA certificates with weak private keys issued by the eMudhra certificate authority. A man-in-the-middle attacker could use this flaw to issue certificates for arbitrary host names signed by the weak intermediate CA certificates, which would be considered trusted by a TLS/SSL client using system CA store and cause such clients to connect to malicious sites. Due to inability to only distrust specific intermediate certificates in all clients using the system CA store, root CA certificates of authorities that signed weak intermediate CA certificates are being removed.

  3. CVE-2026-92824 6.2 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9 · Red Hat Hardened Images

    A flaw was found in libmodulemd. In the module stream v2 rpm-map emission path, an inner loop incorrectly uses the count of digest algorithms as its bound instead of the number of checksums in the current digest table. Crafted modulemd v2 metadata with multiple digest types can trigger an out-of-bounds read during YAML serialization, typically causing a crash and resulting in a denial of service.

  4. CVE-2026-92823 6.2 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9 · Red Hat Hardened Images

    A flaw was found in libmodulemd. In builds with rpmio support enabled, compressed modulemd YAML is decompressed through a custom read handler that does not enforce a cumulative decompressed-size limit before parsing. An attacker who can supply a highly compressible compressed YAML file can cause excessive CPU and memory consumption, resulting in a denial of service.

  5. CVE-2026-92822 6.2 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9 · Red Hat Hardened Images

    A flaw was found in libmodulemd. When parsing module metadata, the xmd field is converted into nested GVariant values through recursive YAML mapping and sequence helpers without a recursion-depth or node-count limit. An attacker who can supply crafted modulemd YAML with deeply nested xmd content can cause stack exhaustion or excessive resource consumption, resulting in a denial of service.

  6. CVE-2026-114038 5.1 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in device-mapper-multipath. A local user can trigger an out-of-bounds read by sending a command with a format string ending in a trailing percent character to the multipath daemon. This issue can allow the user to expose unintended daemon memory, leading to information disclosure, or cause the daemon to crash, resulting in a Denial of Service (DoS).

  7. CVE-2026-16460 7.4 Élevée

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9 · Red Hat Hardened Images

    A flaw was found in bootc and ostree. Already-staged deployments are finalized without revalidating the deployment's container image against the current containers signature policy. Unsigned OS content staged under a prior permissive policy can remain bootable after policy is hardened to reject unsigned images, leading to full host compromise on reboot.

  8. CVE-2026-89096 5.9 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in nfs-utils. An unauthenticated remote attacker can trigger a Denial of Service (DoS) by sending repeated state notification requests to an exposed rpc.statd service. The service fails to properly release memory allocated during callback processing, leading to continuous memory growth. Sustained requests can exhaust system resources, eventually causing the service to degrade or crash.

  9. CVE-2026-85977 5.3 Moyenne

    Red Hat Hardened Images · Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7

    A flaw was found in libtirpc. A remote attacker can exploit this vulnerability by sending specially crafted PMAPPROC_DUMP replies to a client application that uses the pmap_getmaps() function against an attacker-controlled host. This unbounded decoding can lead to excessive memory and CPU allocation, causing the client process to experience a Denial of Service (DoS) due to resource exhaustion.

  10. CVE-2026-85231 6.5 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in libtirpc. An authenticated remote attacker could exploit this vulnerability by sending oversized wrapped data requests to an RPC (Remote Procedure Call) service configured with RPCSEC_GSS (Remote Procedure Call Security-Generic Security Service) integrity or privacy. This can lead to unbounded memory allocation, resulting in a Denial of Service (DoS) by exhausting system resources and causing the service to become unstable or terminate.

  11. CVE-2026-89098 5.5 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in nfs-utils. The fsidd daemon improperly handles input received over its local domain socket by relying on program assertions to verify command arguments. A local user can exploit this vulnerability by sending a malformed request lacking the required arguments to trigger an assertion failure. This causes the daemon to crash, resulting in a Denial of Service (DoS) for filesystem identifier lookup services until restarted.

  12. CVE-2026-111555 6.0 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    A flaw was found in luksmeta. Improper boundary validation of metadata slots allows an attacker capable of supplying or modifying a disk header to redirect wipe or load operations outside the intended metadata area. An attacker could exploit this vulnerability by providing a crafted header with valid checksums to overwrite or zero out encrypted payload data, resulting in persistent data loss and corrupted storage. Exploitation typically requires privileged access to modify raw block devices or the ability to induce an administrator to process an untrusted disk image.

  13. CVE-2026-104715 7.8 Élevée

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in cifs-utils. This flaw allows an unprivileged local user to achieve privilege escalation. When a privileged service mounts a Common Internet File System (CIFS) share using a user-controlled credentials file, input values are not properly sanitized before being assembled into mount options. A local attacker can exploit this vulnerability to inject unauthorized mount options, allowing them to bypass permission checks and execute files with administrative (root) privileges.

  14. CVE-2026-92982 8.5 Élevée

    Red Hat Ansible Automation Platform 2.6 · Red Hat Ansible Automation Platform 2.7 · Red Hat Migration Toolkit for Applications 8 · Red Hat Migration Toolkit for Containers

    A flaw was found in Ansible Operator Plugins. A low-privileged Kubernetes user can exploit a Jinja2 template injection vulnerability by crafting malicious custom resource (CR) specification values. These values are processed by Ansible without proper sanitization, allowing embedded Jinja2 expressions to be executed within the operator pod. This can lead to arbitrary code execution and privilege escalation, granting the attacker control over the operator's service account with cluster-wide permissions.

  15. CVE-2026-86847 6.5 Moyenne

    Red Hat Fast Datapath for RHEL 10 · Red Hat Fast Datapath for RHEL 8 · Red Hat Fast Datapath for RHEL 9 · Red Hat Enterprise Linux 10

  17. CVE-2026-86845 6.5 Moyenne

    Red Hat Fast Datapath for RHEL 10 · Red Hat Fast Datapath for RHEL 8 · Red Hat Fast Datapath for RHEL 9 · Red Hat Enterprise Linux 10

    A flaw was found in DPDK lib/vhost vhost-crypto. Session cleanup can leave a stale cached session pointer, and the data path does not check the session type before attaching it, leading to use-after-free or type confusion in the host vhost-crypto backend.

  18. CVE-2026-86567 8.8 Élevée

    Red Hat Fast Datapath for RHEL 10 · Red Hat Fast Datapath for RHEL 8 · Red Hat Fast Datapath for RHEL 9 · Red Hat Enterprise Linux 10

    A flaw was found in DPDK lib/vhost. The VDUSE handler fails to invalidate vring pointers when the IOTLB is invalidated, leading to use-after-unmap.

  19. CVE-2026-86566 6.5 Moyenne

    Red Hat Fast Datapath for RHEL 10 · Red Hat Fast Datapath for RHEL 8 · Red Hat Fast Datapath for RHEL 9 · Red Hat Enterprise Linux 10

    A flaw was found in DPDK lib/vhost. A guest with runt RX descriptors can underflow the copy length in vhost enqueue, causing a denial of service in a shared vhost backend such as OVS-DPDK.

  20. CVE-2026-86565 8.2 Élevée

    Red Hat Fast Datapath for RHEL 10 · Red Hat Fast Datapath for RHEL 8 · Red Hat Fast Datapath for RHEL 9 · Red Hat Enterprise Linux 10

    A flaw was found in DPDK lib/vhost. A guest can desynchronize virtqueue size from inflight descriptor table size, causing an out-of-bounds write in the host vhost process.

  21. CVE-2026-86563 7.8 Élevée

    Red Hat Fast Datapath for RHEL 10 · Red Hat Fast Datapath for RHEL 8 · Red Hat Fast Datapath for RHEL 9 · Red Hat Enterprise Linux 10

    Red Hat Fast Datapath for RHEL 10 · Red Hat Fast Datapath for RHEL 8 · Red Hat Fast Datapath for RHEL 9 · Red Hat Enterprise Linux 10

    A flaw was found in the DPDK GSO library. When software GSO copies packet headers into a new mbuf, it does not check that the header fits in the source first segment or in the destination buffer, and a header longer than the configured GSO segment size can underflow the payload-size calculation. A remote or guest-supplied packet processed with software GSO can trigger an out-of-bounds read or write.

  24. CVE-2026-93683 6.4 Moyenne

    Red Hat Fast Datapath for RHEL 10 · Red Hat Fast Datapath for RHEL 8 · Red Hat Fast Datapath for RHEL 9 · Red Hat Enterprise Linux 10

    A flaw was found in the DPDK vhost library. When handling a virtio indirect descriptor table, the host reads the table length more than once from guest memory and can allocate a host copy before validating that length. A guest that changes the length between those reads, or that supplies an out-of-range next index on a small host copy in the vDPA relay path, can cause the host vhost process to walk past the validated mapping or heap copy. That can crash or disrupt the vhost process. Out-of-bounds bytes are consumed as descriptor fields for GPA translation and are not returned to the guest as payload. This is a residual issue in the non-contiguous indirect descriptor copy path introduced as part of the CVE-2018-1059 fix.

  25. CVE-2026-86561 6.5 Moyenne

    Red Hat Fast Datapath for RHEL 10 · Red Hat Fast Datapath for RHEL 8 · Red Hat Fast Datapath for RHEL 9 · Red Hat Enterprise Linux 10

  26. CVE-2026-109968 5.5 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    A flaw was found in the clevis PKCS#11 pin. The clevis-pkcs11-afunix-socket-unlock daemon logs LUKS disk encryption passphrases in plaintext to a log file. The log file is created without restrictive permissions, making it world-readable under the default process umask. A local attacker can read the log file to obtain the LUKS passphrase.

  27. CVE-2026-104795 8.8 Élevée

    Red Hat OpenShift Container Platform 4.21

    The insights-runtime-extractor runs as a privileged DaemonSet (`hostPID: true`) that scans container processes for runtime fingerprinting. When scanning a container, the coordinator: 1. **fork()s** a child process 2. **setns()** into the target container's PID and mount namespaces 3. **fchdir()** back to an orphaned FD pointing at the extractor's own root filesystem (where `/crio.sock` is hostPath-mounted) 4. Calls **only `seteuid(target_uid)`** — changing the effective UID but leaving the **real UID and saved-set-UID at 0** and **retaining the permitted capability set** 5. The `check_no_privileged_perms()` guard inspects only the Effective capability set (so it passes), and is **skipped entirely when the target runs as uid 0** 6. The `VersionExecutable` fingerprint invokes `fpr_kind_executable` with `process.command_line[0]` — the target's argv[0], read from `/proc/<pid>/cmdline` and **fully controlled by the workload** 7. `fpr_kind_executable` calls `exec.Command(executable, "--version").Output()` — executing the **workload's own binary** inside the workload's mount namespace while **ruid=0 in the host user namespace** The executed process can call `setuid(0)` to restore full root with `CAP_SYS_ADMIN`, and inherits the orphaned cwd which resolves into the extractor container's filesystem containing the host CRI-O socket. ## Affected Code ### 1. Insufficient privilege drop (Rust — extractor coordinator) **File:** `extractor/src/insights_runtime_extractor.rs` ```rust // Lines 139-146 — seteuid-only drop, guard skipped for root containers join_process_namespaces(process.pid)?; change_dir(current_dir); switch_user(*process.uid)?; if *process.uid != 0 { perms::check_no_privileged_perms() .expect("Must not have privileged permissions to run fingerprints"); } fingerprint::run_fingerprints(&config, out_dir, &process); ``` ```rust // Lines 182-185 — only effective UID changed; ruid/suid stay 0 fn switch_user(uid: u32) -> Result<(), ScannerError> { debug!("... Becoming user: {uid}"); seteuid(uid.into()).map_err(|e| ScannerError::Errno(e)) } ``` ### 2. Execution of untrusted binary (Go — fingerprint) **File:** `fingerprints/pkg/utils/file.go` ```go // Lines 75-80 — executes a path taken verbatim from workload's argv[0] func GetExecutableVersionOutput(executable string) (string, error) { out, err := exec.Command(executable, "--version").Output() if err != nil { return "", err } return string(out), nil } ``` ### 3. Workload-controlled path forwarded (Rust — version_executable) **File:** `version_executable.rs` ```rust // Lines 29-34 — workload-controlled command_line[0] forwarded to fingerprint return Some(vec![ fpr_kind_executable, out_dir.to_string(), String::from(&process.command_line[0]), String::from(&version_executable.runtime_kind_name), ]); ``` ## Attack Pattern **Attacker:** Any tenant able to schedule a pod (unprivileged, any namespace) **Victim:** The node running the insights-runtime-extractor DaemonSet **Trigger:** Automatic — the DaemonSet scans all container processes on the node **Attack sequence:** 1. Attacker creates a pod whose process name matches a configured versioned-executable pattern (`node`, `python`, `python3`, `MainThread`, or contains `java`) 2. The pod's main binary (at the path matching argv[0]) is a malicious executable that calls `setuid(0)` to restore root 3. When the insights operator triggers a scan, the DaemonSet forks, enters the attacker's mount namespace, and executes the attacker's binary with ruid=0 4. The attacker's code regains full root with `CAP_SYS_ADMIN` in the host user namespace 5. The inherited cwd contains the host CRI-O socket → full node compromise

  28. CVE-2026-109971 4.7 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    A flaw was found in the clevis PKCS#11 pin. The clevis-decrypt-pkcs11 script passes the PKCS#11 token PIN as a command-line argument to pkcs11-tool, making it visible to any local user through process listing or the /proc filesystem.

  29. CVE-2026-109970 4.7 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    A flaw was found in the clevis PKCS#11 pin. The clevis-luks-pkcs11-askpin script writes the PKCS#11 token PIN in plaintext to a file without setting restrictive permissions. Under the default process umask, the file is world-readable. Additionally, the PIN file is not reliably cleaned up if the decryption script exits early, leaving the PIN accessible indefinitely.

  30. CVE-2026-109969 4.7 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    A flaw was found in the clevis PKCS#11 pin. The clevis-pkcs11-afunix-socket-unlock daemon creates AF_UNIX sockets without explicit permission restrictions or peer credential verification. Under a permissive process umask, any local user can connect to the control socket and inject arbitrary device/key pairs, or connect to the data socket to receive LUKS passphrases.

  31. CVE-2026-110036 3.3 Faible

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in device-mapper-persistent-data. A local attacker can cause a Denial of Service (DoS) by inducing a user or system tool to process crafted device metadata containing an excessively large block index. An arithmetic error in the synchronous block reading logic causes the application to panic and unexpectedly terminate.

  32. CVE-2026-109976 4.7 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    A flaw was found in the clevis PKCS#11 pin. The clevis-pkcs11-afunix-socket-unlock daemon crashes when an AF_UNIX client connects to the data socket without a bound address, due to an integer underflow in the getpeername result handling. This causes a denial of service, preventing LUKS disk decryption from completing during boot.

  33. CVE-2026-75888 7.7 Élevée

    Red Hat OpenShift Container Platform 4.19 · Red Hat OpenShift Container Platform 4.20 · Red Hat OpenShift Container Platform 4.21 · Red Hat OpenShift Container Platform 4.22

    A flaw was found in the OpenShift console. An authenticated console user can exploit a Server-Side Request Forgery (SSRF) vulnerability by providing a specially crafted Helm chart URL without proper validation. This allows the user to make the console pod fetch arbitrary URLs, potentially leading to the disclosure of sensitive information through error messages or enabling blind port scanning within the cluster.

  34. CVE-2026-107935 9.3 Critique

    Red Hat Build of Podman Desktop · Red Hat Certification Program for Red Hat Enterprise Linux 9 · Red Hat Edge Manager 1 · Red Hat Enterprise Linux 10

    A path traversal vulnerability was found in gvproxy, the network forwarder provided by the gvisor-tap-vsock package. The unauthenticated /services/forwarder/expose endpoint does not validate the caller-supplied socket path, allowing an attacker to delete arbitrary files on the host system.

  35. CVE-2026-89091 8.8 Élevée

    Red Hat Migration Toolkit for Applications 8 · Red Hat Migration Toolkit for Virtualization · Red Hat OpenShift Service Mesh 3 · Red Hat Advanced Cluster Management for Kubernetes 2

    A flaw was found in ansible-core. When installing a collection with `ansible-galaxy collection install`, the archive extractor validates member paths using lexical path normalisation (os.path.abspath) instead of resolving symbolic links (os.path.realpath), and it performs no containment check on symlink-typed directory members before creating them. A crafted collection tarball can chain symlink directory entries so that a subsequent file member is written outside the intended destination directory. This allows an attacker who can get a victim to install a malicious collection to overwrite arbitrary files with the privileges of the user running ansible-galaxy, leading to code execution on the control node. This is a bypass of the fix for CVE-2020-10691.

  36. CVE-2026-93017 7.7 Élevée

    Red Hat OpenShift Container Platform 4.19 · Red Hat OpenShift Container Platform 4.20 · Red Hat OpenShift Container Platform 4.21 · Red Hat OpenShift Container Platform 4

    The `insights-operator-gather` ClusterRole grants the operator's service account read access to secrets in the core API group with no namespace or resourceNames restriction — therefore, access to every secret in every namespace in the cluster. Ref: https://github.com/openshift/insights-operator/blob/8f15e3157ff09f54ab22801f5b21da35a195cc6d/manifests/03-clusterrole.yaml#L368-L373 ``` - apiGroups: - "" resources: - secrets verbs: - get - list ``` By spawning a pod with the gather service account mounted, an attacker will be able to access any secret in any namespace. ``` spec: serviceAccountName:"gather" ```

  37. CVE-2026-107565 5.1 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    A flaw was found in luksmeta. A local attacker with administrative privileges can cause data corruption when saving metadata to a Linux Unified Key Setup (LUKS) device. Due to incorrect boundary calculations and flawed overlap detection, new metadata entries can be written beyond available free space or over existing records. This issue can corrupt stored encrypted payload data or existing metadata, potentially rendering the affected data inaccessible.
