CVE-2026-3086

A flaw was found in GStreamer. A remote attacker could exploit this out-of-bounds write vulnerability by providing specially crafted H.266 video data. This issue, specifically within the processing of Adaptation Parameter Set (APS) units, stems from insufficient validation of user-supplied data, leading to a write beyond the allocated buffer. Successful exploitation allows the attacker to execute arbitrary code on the system where GStreamer is running.
