CVE-2026-124312

Description

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.
