Doc Text:
A flaw was found in FFmpeg. A memory leak vulnerability in the libxevd decoder component allows an attacker to cause a Denial of Service (DoS) through memory exhaustion. By tricking an application into processing a specially crafted Essential Video Coding (EVC) stream containing non-frame data packets, an attacker can trigger unreleased memory allocations, potentially leading to application failure.

Description OSIDB Bzimport 2026-11-10 20:01:24 UTC
FFmpeg through 9.0.2 contains a memory leak vulnerability in libxevd_receive_frame() in libavcodec/libxevd.c that fails to free pkt_au when an access unit produces no picture. Attackers can supply a crafted EVC stream with many access units containing only parameter sets or non-frame NAL units to exhaust memory in the decoding application.
