CVE-2026-64832 is a double-free vulnerability in FFmpeg versions 4.4 through 8.1.2 in the NVIDIA NVDEC hardware-decoding implementation. When decoder surfaces are exhausted, an error path in ff_nvdec_start_frame_sep_ref releases frame-description private data through nvdec_fdd_priv_free, after which the calling layer releases the same data again. This results in a double-free of the underlying decoder context when crafted video content is processed by an FFmpeg-based application using NVDEC acceleration.
