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.

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.

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.

CVE-2026-102623 6.5 Moyenne
Red Hat OpenShift Virtualization 4
A flaw was found in KubeVirt. An authenticated user with permission to create Virtual Machine Instances (VMIs) can cause a Denial of Service (DoS) by submitting a virtual machine definition with an empty ephemeral volume. The virt-controller component fails to properly validate the volume configuration, leading to an unhandled exception and application crash during processing. Because the malformed definition persists in the cluster, the controller enters a continuous crash loop, disrupting virtual machine lifecycle operations across the entire environment.
