Summary

A double-free vulnerability in the NVIDIA NVDEC hardware decoder in FFmpeg versions 4.4 through 8.1.2. Attackers can trigger memory corruption by supplying a crafted video file, causing a double-free of the decoder context.

Risk Assessment

An attacker could cause memory corruption, potentially leading to crashes or code execution in applications using NVDEC acceleration.

Recommendation

Upgrade FFmpeg to version 8.1.3 or later.

Original NVD description (English source)

FFmpeg versions 4.4 through 8.1.2 contain a double-free vulnerability in the NVIDIA NVDEC hardware decoder within libavcodec/nvdec.c that allows attackers to trigger memory corruption by supplying a crafted video file. When no decoder surfaces remain, the ff_nvdec_start_frame_sep_ref error path frees memory via nvdec_fdd_priv_free while the calling layer subsequently frees the same frame description data, resulting in a double-free of the underlying decoder context in any FFmpeg-based application using NVDEC hardware-accelerated decoding.
