CVE-2026-125216
Discovered by AISLEPUBLISHEDCWE-476
Description
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.
