Last modified
CVE-2026-125244 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. FFmpeg before 8.1.3 and 9.x before 9.0.2 contains an out-of-bounds write vulnerability in the VVC decoder's sh_entry_points() function in libavcodec/vvc/ps.c. Attackers can supply a crafted VVC (H.266) bitstream whose SPS/PPS tile and WPP layout produces excess entry points, overflowing entry_point_start_ctu and corrupting decoder memory.. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
