MEDIUM 6.8 NVD
CVE-2026-125200
FFmpeg through 9.0.2 contains a memory leak vulnerability in libavcodec/libx265.c because libx265_encode_frame() never frees the rpu.payload allocated by ff_dov
FFmpeg through 9.0.2 contains a memory leak vulnerability in libavcodec/libx265.c because libx265_encode_frame() never frees the rpu.payload allocated by ff_dovi_rpu_generate(). Attackers can supply crafted Dolby Vision HEVC or AV1 files that leak one RPU allocation per encoded frame during libx265 transcoding, causing unbounded memory growth and denial of service.
