CVE-2026-124310 | BDVDB-2026-401799 Detail
fraunhoferhhivvdec
Description#
Fraunhofer HHI VVdeC before 3.2.1 contains an out-of-bounds read vulnerability that allows attackers to crash the decoder by supplying bitstreams with overlapping slice CTU coverage. Attackers can code a CTU in a second slice so a bi-predicted BDOF coding unit carries a negative reference index, causing Slice::getRefPic to read outside m_apcRefPicList and crash decoding.
Impact#
Per CVSS v3.1: confidentiality impact low, integrity impact none, availability impact high. Attack vector: local.
Weaknesses#
- CWE-129 Improper Validation of Array Index
