  1. CVE-2026-82327 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 libsolv, a dependency-resolution library used by RPM-based package managers such as dnf and zypper to work with .solv repository cache files. When libsolv rewrites a .solv cache file, it reads directory-id values from the file's compressed filelist data without validating that they fall within the expected range. A corrupted or specially crafted .solv cache file (for example, one left in a torn state after an unclean system shutdown) can cause an out-of-bounds memory write when a tool such as dnf, yum, or zypper next processes it. Successful exploitation is expected to result in a crash of the affected tool (denial of service); it is not expected to allow arbitrary code execution because the out-of-bounds write always stores a fixed, non-attacker-controlled value.

  2. CVE-2026-74247 7.1 Élevée

    Red Hat OpenShift Update Service · Red Hat Quay 3 · Redhat openshift update service · Redhat quay

    A flaw was found in Red Hat Quay. A user with FEATURE_BUILD_SUPPORT enabled and repository write access can exploit a Server-Side Request Forgery (SSRF) vulnerability within the build API. This allows the user to provide a malicious URL, causing the Quay builder to make requests to internal network addresses. Such an action could lead to the disclosure of sensitive internal information.

  3. CVE-2026-74245 7.5 Élevée

    Red Hat OpenShift Update Service · Red Hat Quay 3 · Redhat openshift update service · Redhat quay

    A flaw was found in Red Hat Quay's exported logs feature. An unauthenticated attacker with a valid file ID could download exported action logs without proper authorization. While file IDs are complex, they can be intercepted from plaintext email or webhook callbacks. This vulnerability leads to information disclosure, potentially exposing sensitive data such as usernames, email addresses, IP addresses, and action-specific metadata.

  4. CVE-2026-74244 7.5 Élevée

    Red Hat OpenShift Update Service · Red Hat Quay 3 · Redhat openshift update service · Redhat quay

    A flaw was found in Red Hat Quay's Stripe billing webhook handler. This vulnerability allows an unauthenticated attacker to forge billing events by sending crafted JSON requests to the `/webhooks/stripe` endpoint without validating the Stripe-Signature header. Successful exploitation can lead to the unauthorized resetting of a namespace's build quota to its maximum and trigger unsolicited billing emails to namespace administrators.

  5. CVE-2026-74243 8.2 Élevée

    Red Hat OpenShift Update Service · Red Hat Quay 3 · Redhat openshift update service · Redhat quay

    A flaw was found in Red Hat Quay. When the SECURITY_SCANNER_V4_PSK (pre-shared key) is not set, a remote unauthenticated attacker can send POST requests to the security scanner notification endpoint. This allows the attacker to flood the notification queue and inject path traversal characters into Clair API URL paths. The primary consequence is worker resource exhaustion and blind path manipulation on the configured Clair host, potentially leading to a denial of service.

  6. CVE-2026-74242 4.4 Moyenne

    Red Hat OpenShift Update Service · Red Hat Quay 3 · Redhat openshift update service · Redhat quay

    A flaw was found in Red Hat Quay. An administrator of any repository, by knowing or guessing a target notification's Universally Unique Identifier (UUID), can read the notification configuration, including sensitive details like webhook URLs, Slack tokens, and email addresses. This vulnerability also allows them to trigger test notifications for another repository. This could lead to unauthorized information disclosure and potential misuse of notification services.

  7. CVE-2026-74241 6.5 Moyenne

    Red Hat OpenShift Update Service · Red Hat Quay 3 · Redhat openshift update service · Redhat quay

    A flaw was found in Red Hat Quay's external Lightweight Directory Access Protocol (LDAP) authentication handling. When an LDAP referral is returned during authentication, the system does not properly escape the username input. This allows an attacker to inject LDAP filter metacharacters, enabling user-existence oracle attacks at the referral Directory Name (DN). This could also potentially influence which DN is used for password binding in multi-domain Active Directory environments.

  8. CVE-2026-74240 5.4 Moyenne

    Red Hat OpenShift Update Service · Red Hat Quay 3 · Redhat openshift update service · Redhat quay

    A flaw was found in Red Hat Quay's JWT (JSON Web Token) validation for federated robot accounts and single sign-on (SSO) authentication. Multiple issues related to audience verification and the enforcement of `azp` and `sub` claims were identified. These flaws could allow an attacker with a validly-signed token from the same identity provider to bypass configured security restrictions. This bypass could lead to unauthorized access by circumventing intended audience, subject, or authorized-client limitations.

  9. CVE-2026-15816 7.5 Élevée

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 10.0 Extended Update Support · Red Hat Enterprise Linux 6 Extended Lifecycle Support - EXTENSION · Red Hat Enterprise Linux 7 Extended Lifecycle Support

    A flaw was found in dracut. The die() error-handling function writes its message into a shell script under the initramfs emergency-hook directory without properly shell-quoting it. When the message contains data derived from the DHCP ROOT_PATH option, an attacker on the adjacent network who controls a rogue DHCP server can inject a command-substitution sequence that executes as root the next time dracut sources its emergency hook scripts during standard boot-failure handling.

  10. CVE-2026-71227 5.1 Moyenne

    Stephan Muelle libkcapi · Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 10.0 Extended Update Support · Red Hat Enterprise Linux 8

    A flaw was found in libkcapi. A local attacker can influence an application that uses the Asynchronous Input/Output (AIO) interface. By reusing an AIO-enabled handle after a prior completion error, the _kcapi_aio_read_all() function can enter a non-terminating wait loop. This can lead to a persistent denial of service, making the affected application or thread unresponsive.
