CVE-2026-86476 2 Red Hat, Redhat 3 Enterprise Linux, Enterprise Linux, Rhel Els 2026-11-10 8.4 High
A flaw was found in gst-plugins-base. A heap buffer overflow can be triggered when processing video buffers whose attached GstVideoMeta metadata declares plane strides and offsets that exceed the actual backing memory allocation. The metadata is not range-checked during deserialization, and the video frame mapping code does not verify that the declared plane geometry fits within the buffer before allowing consumers to read or write video data. A local attacker who controls the sending side of a GStreamer inter-process IPC pipeline can deliver a crafted buffer carrying fabricated strides, causing the receiving process to read or write beyond heap boundaries. Successful exploitation can cause a denial of service or potentially allow code execution within the affected process.
CVE-2026-100229 2 Red Hat, Redhat 3 Enterprise Linux, Enterprise Linux, Rhel Els 2026-11-10 6.5 Medium
A flaw was found in GStreamer's H.266 codec parser library (libgstcodecparsers). An out-of-bounds write vulnerability exists in the DCI parsing function, where a reserved field value is incorrectly accepted, causing the parser to write beyond the bounds of an internal structure. An attacker could exploit this by providing a specially crafted H.266 bitstream to a third-party application that uses this library API, potentially causing a crash or memory corruption. No standard GStreamer pipeline element currently invokes the affected code path.
CVE-2026-62438 2 Red Hat, Redhat 3 Enterprise Linux, Enterprise Linux, Rhel Els 2026-11-10 6.1 Medium
A flaw was found in GIMP. An attacker can cause a Denial of Service (DoS) or potentially disclose sensitive memory contents by convincing a user to open or preview a specially crafted Bohemia Interactive (PAA) texture file. Due to an integer overflow when calculating image dimensions during file decompression, the application allocates an undersized memory buffer. Subsequent processing reads memory past the buffer boundary, terminating the plug-in process unexpectedly.
CVE-2026-92823 2 Red Hat, Redhat 7 Enterprise Linux, Enterprise Linux, Hardened Images and 4 more 2026-11-10 6.2 Medium
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.
CVE-2026-92822 2 Red Hat, Redhat 7 Enterprise Linux, Enterprise Linux, Hardened Images and 4 more 2026-11-10 6.2 Medium
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.
CVE-2026-125040 2 Red Hat, Redhat 3 Enterprise Linux, Enterprise Linux, Rhel Els 2026-11-10 6.5 Medium
A flaw was found in the SRT and WebVTT subtitle parser in GStreamer's gst-plugins-base. While sanitizing inline subtitle markup, the parser repeatedly searches the remaining text with unanchored regular expressions. A crafted subtitle cue with a long line of unmatched markup-like text can force quadratic CPU use and make a GStreamer-based application unresponsive.
CVE-2026-125652 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2026-11-10 6.8 Medium
A flaw was found in the keycloak-services component of Keycloak, which provides the core authentication and authorization logic for the identity provider. The issue occurs when a user initiates a login after visiting the password reset page, causing the system to skip mandatory security checks for Proof Key for Code Exchange (PKCE). This could allow an attacker who intercepts a login code to gain unauthorized access to the user's account without needing the required security verifier.
CVE-2026-120749 2 Red Hat, Redhat 5 Enterprise Linux, Enterprise Linux, Hardened Images and 2 more 2026-11-10 6.2 Medium
A flaw was found in D-Bus. With a privileged Monitoring client attached (for example dbus-monitor or busctl monitor), an unprivileged local user can cause dbus-daemon to abort if a driver-originated broadcast such as NameOwnerChanged or ActivatableServicesChanged cannot be delivered to a recipient (for example due to a deny rule or an exceeded outgoing message queue). Driver broadcasts still use serial 0; when delivery fails, composing the monitor error reply asserts reply_serial != 0 and aborts the daemon.
CVE-2026-125041 2 Red Hat, Redhat 3 Enterprise Linux, Enterprise Linux, Rhel Els 2026-11-10 5.5 Medium
A flaw was found in GStreamer's gst-plugins-good MOV/MP4 demuxer. When processing an uncompressed video track, qtdemux fails to validate the declared row alignment and chroma geometry before using them to build a video buffer layout. A crafted file can cause an out-of-bounds heap read while the sample is copied, potentially crashing the application and causing denial of service.
CVE-2026-112318 2 Red Hat, Redhat 5 Enterprise Linux, Enterprise Linux, Hardened Images and 2 more 2026-11-09 6.5 Medium
The policy RPC stubs in kadmin/server/server_stubs.c in MIT Kerberos 5 (aka krb5) 1.5.3 and later do not reject a NULL policy name decoded by xdr_nullstring(), which allows remote authenticated users to cause a denial of service (kadmind crash via NULL pointer dereference) by sending a policy request with an empty policy name that reaches authorization checks or logging code.
CVE-2026-19706 1 Redhat 3 Assisted Installer, Multicluster Engine, Openshift 2026-11-09 8.3 High
During ABI bootstrap, the bootstrap node's approve-csr.service approves and signs every CSR without identity validation. An attacker on the install network can retrieve the unauthenticated Ignition file (ports 22623/22624), extract a limited kubeconfig, submit a CSR for CN=system:admin, receive the signed certificate, and gain full cluster-admin access. Exploitable only during the narrow bootstrap window.
CVE-2026-112322 1 Redhat 3 Enterprise Linux, Hummingbird, Rhel Els 2026-11-09 7.5 High
clean_client() in lib/rpc/svc_auth_gssapi.c in MIT Kerberos 5 (aka krb5) restarts its scan from the head of the client list after each removal, resulting in quadratic CPU cost. Remote attackers can cause a denial of service (CPU consumption in kadmind) by accumulating a large number of AUTH_GSSAPI client entries.
CVE-2026-112321 1 Redhat 3 Enterprise Linux, Hummingbird, Rhel Els 2026-11-09 7.5 High
The AUTH_GSSAPI handler in lib/rpc/svc_auth_gssapi.c in MIT Kerberos 5 (aka krb5) does not free decoded arguments on certain error paths, which allows remote attackers to cause a denial of service (memory exhaustion in kadmind) via crafted AUTH_GSSAPI_INIT requests that trigger authentication failures.
CVE-2026-112316 1 Redhat 3 Enterprise Linux, Hummingbird, Rhel Els 2026-11-09 6.5 Medium
xdr_krb5_tl_data() in lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (aka krb5) does not free partially decoded data on failure, which allows remote authenticated users to cause a denial of service (memory leak in kadmind) via crafted RPC requests that trigger a decode failure.
CVE-2026-76166 1 Redhat 7 Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Expansion Pack, Jboss Enterprise Web Server and 4 more 2026-11-09 4.3 Medium
A flaw was found in mod_cluster's AdvertiseListenerImpl (org.jboss.modcluster core module). A single crafted UDP multicast datagram with a valid HTTP status line and a "Server:" header but without the "Date:", "Digest:", and "Sequence:" headers triggers a NullPointerException in verifyDigest() that is not caught by the worker thread's exception handler. This causes the advertise listener thread to terminate permanently. The failure is silent (isListening() continues to return true) and persists until the node is restarted. The crash occurs before the AdvertiseSecurityKey comparison, so deployments with a configured security key are still affected.
CVE-2026-12977 1 Redhat 4 Jboss Enterprise Application Platform, Jboss Fuse, Jbosseapxp and 1 more 2026-11-09 8.8 High
A flaw was found in the deployment-operation family of WildFly Core. Certain handlers, such as upload-deployment-url, lack proper sensitivity classification, allowing an administrator with the restricted "Maintainer" role to read sensitive configuration files. This can lead to the exfiltration of credentials and full administrative control (SuperUser) of the server.
CVE-2026-112317 1 Redhat 3 Enterprise Linux, Hummingbird, Rhel Els 2026-11-09 5.3 Medium
krb5_ktkdb_get_entry() in lib/kdb/keytab.c in MIT Kerberos 5 (aka krb5) 1.2.8 and later does not free decrypted key material when a post-decryption check fails, which allows remote attackers to cause a denial of service (memory leak in the KDC or kadmind) via requests that repeatedly trigger key decryption failures.
CVE-2026-112314 1 Redhat 3 Enterprise Linux, Hummingbird, Rhel Els 2026-11-09 7.5 High
clnttcp_call() in lib/rpc/clnt_tcp.c in MIT Kerberos 5 (aka krb5) does not free the RPC reply verifier between retries, which allows remote attackers to cause a denial of service (memory leak in GSS-RPC client programs) by injecting RPC replies with mismatched XIDs or by triggering authentication retries.
CVE-2026-92092 1 Redhat 2 Openshift, Openshift Container Platform 2026-11-09 7.4 High
A flaw was found in openshift-ansible. The installer container's `run` script downloads and executes remote inventory and dynamic scripts without integrity verification. A remote attacker, by performing a Man-in-the-Middle (MITM) attack or compromising the HTTP server providing these scripts, could substitute an arbitrary executable. This malicious executable would then run with the installer's user ID (UID) and full cluster-provisioning privileges, leading to arbitrary code execution.
CVE-2026-122056 1 Redhat 3 Enterprise Linux, Hummingbird, Rhel Els 2026-11-09 5.9 Medium
A flaw was found in OpenSCAP. A heap-based buffer overflow can occur when processing a specially crafted Extensible Configuration Checklist Description Format (XCCDF) document using the sds-compose option. An attacker could exploit this vulnerability to corrupt memory, resulting in an application crash and a Denial of Service (DoS).
