Last modified

CVE-2026-125216 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. FFmpeg through 9.0.2 contains a NULL pointer dereference vulnerability in libavcodec/dpxenc.c that allows attackers to crash the process via unvalidated bits_per_raw_sample for RGB48 input. Attackers can supply a 12-bit RGB image, such as JPEG 2000, that when transcoded to DPX selects encode_gbrp12() and dereferences NULL plane pointers, causing denial of service.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
