CVE-2026-124312
Published:November 07, 2026
Updated:November 09, 2026
Fraunhofer HHI VVdeC through 3.2.1 contains a heap out-of-bounds read vulnerability that allows attackers to crash the decoder by supplying a collocated picture of different resolution. Attackers can craft a VVC bitstream enabling TMVP with a smaller collocated reference picture, causing getColInfo to read past the colMotion allocation when error concealment is enabled.
