DescriptionCVE.org

A flaw was found in GStreamer's gst-plugins-bad package. When processing a specially crafted H.264 video file containing malformed MVC or SVC extension slice NAL units, a 1-byte heap out-of-bounds read can occur during parsing. This happens when the parser attempts to check slice boundary information without first verifying that the NAL unit contains enough data beyond the extension header. An attacker could exploit this by tricking a user into opening a malicious H.264 video file, potentially causing the application to crash or leak a single byte of heap memory.

AnalysisAI

Heap out-of-bounds read in GStreamer's gst-plugins-bad H.264 parser allows an attacker to crash a media application or leak a single byte of heap memory by tricking a victim into opening a specially crafted H.264 video file containing malformed MVC or SVC extension slice NAL units. Affected systems span Red Hat Enterprise Linux versions 6 through 10 where gst-plugins-bad is installed. No public exploit code has been identified at time of analysis and the vulnerability is absent from CISA KEV; the narrow 1-byte read, required user interaction, and local attack vector substantially limit real-world exploitation impact.

Technical ContextAI

GStreamer is a pipeline-based multimedia framework standard on Linux systems; gst-plugins-bad is its supplementary codec package providing H.264 (AVC) video parsing. H.264 supports Multi-View Coding (MVC) and Scalable Video Coding (SVC) through extension slice NAL (Network Abstraction Layer) units appended to the standard bitstream. The root cause (CWE-125: Out-of-bounds Read) is a missing length-check in the parser: before reading slice boundary information from an extension slice NAL unit, the code does not verify that sufficient data exists beyond the extension header. This allows a malformed NAL unit with truncated payload to cause the parser to read exactly 1 byte past the end of the allocated buffer. CPE data confirms affected deployments as GStreamer gst-plugins-bad on Red Hat Enterprise Linux 6, 7, 8, 9, and 10 (cpe:2.3:a:red_hat:red_hat_enterprise_linux_[6-10]:*:*:*:*:*:*:*:*).

RemediationAI

Apply patches via standard RHEL update mechanisms (yum update gstreamer1-plugins-bad-free or dnf update gstreamer1-plugins-bad-free) once errata are published; monitor the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2026-12892 for patch availability and exact fixed version numbers, as no specific patched release is confirmed in the current intelligence. The upstream fix should also be tracked at https://gitlab.freedesktop.org/gstreamer/gstreamer/-/work_items/5108. As a compensating control on systems that do not require MVC or SVC H.264 content, removing or disabling gst-plugins-bad reduces attack surface, though this will break GStreamer pipelines depending on H.264 codec support - weigh against operational impact before applying. Given the UI:R prerequisite, reinforcing user awareness around opening video files from untrusted sources provides meaningful risk reduction at no operational cost.
