CVE-2026-119729
Gst-plugins-base: gst-plugins-bad: gst-plugins-base/gst-plugins-bad: integer overflow in av1 leb128 parser allows denial of service
A flaw was found in GStreamer. An integer overflow vulnerability in the AV1 LEB128 variable-length integer parser allows a remote attacker to cause a crash in applications that process AV1 media content. By crafting a malformed AV1 bitstream containing an invalid LEB128-encoded value, an attacker can cause integer overflow in the parser, resulting in incorrect length values being used during stream processing, which can lead to a denial of service.
