MEDIUMCVSS v3.1 6.5Vulnerability
CVE-2026-121611
A flaw was found in GStreamer's gst-plugins-bad package. A use of uninitialized memory vulnerability exists in the H.265 (HEVC) bitstream parser when processing Video Parameter Sets that declare more than one HRD (Hypothetical Reference Decoder) parameter set. A remote attacker could exploit this by providing a crafted H.265 media file or stream that, when processed by an application using GStreamer, causes unpredictable parser behavior and may crash the application. This can lead to a denial of service for any application using GStreamer to play back H.265 content.
