gstreamer1-plugins-bad-free: A denial of service vulnerability was found in GStreamer's AV1 codec parser in gst-plugins-bad
CVE-2026-52718 is fixed in 10 products on 1 platform, first by DEBIAN-CVE-2026-52718, released June 24, 2026. It is not reported as exploited. Patch Radar priority: High.
A denial of service vulnerability was found in GStreamer's AV1 codec parser in gst-plugins-bad. The gst_av1_parser_parse_tile_list_obu() function passes a byte count to a bit-reader API that expects a bit count, causing parser desynchronization. A remote attacker could trick a user into opening a specially crafted AV1 media file, triggering an assertion abort and causing the application to crash.
