HighMetricsAV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H
FFmpeg through 9.0.2 contains an integer overflow vulnerability in the VVC decoder alloc frame() function in libavcodec/vvc/refs.c that undersizes the reference picture list allocation on 32-bit builds. Attackers can supply a crafted VVC (H.266) file with a very large number of NAL units per access unit to trigger heap out-of-bounds writes and corrupt memory.
