CVE ID :CVE-2026-52718

Published : June 15, 2026, 7:15 p.m. | 26 minutes ago

Description :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.

Severity: 6.5 | MEDIUM
