Vulnerability Title
Gstreamer1-plugins-bad-free: gstreamer1-plugins-bad-free: out-of-bounds write in gst_h266_parser_parse_dci() due to off-by-one array bound check
Source: CVE Program / CVE List V5
Vulnerability Description
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.
