Last modified

CVE-2026-124310 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. 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.. EPSS estimates a 0.12% chance of exploitation in the next 30 days.
