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.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:3542-1 advisory.

    Update to release 4.4.8.

    - CVE-2026-8461: out-of-bounds write in the MagicYUV decoder can lead to denial of service or remote code     execution       (bsc#1269490).
    - CVE-2026-12706: heap use-after-free read in the RASC video decoder can lead to denial of service     (bsc#1268595).
    - CVE-2026-64830: heap buffer overflow in the VobSub subtitle demuxer can lead to arbitrary code execution       (bsc#1272752).
    - CVE-2026-64832: double-free in the NVIDIA NVDEC hardware decoder can lead to can lead to memory     corruption       (bsc#1272754).
    - CVE-2026-64835: out-of-bounds memory access in the ADX audio decoder can lead to information disclosure     and memory       corruption (bsc#1272758).
    - CVE-2026-66038: exposure of uninitialized heap memory by the LCL/ZLIB video decoder can lead to     sensitive information       disclosure (bsc#1272768).
    - CVE-2026-66039: signed integer overflow in the MACE6 audio decoder can lead to heap corruption and     arbitrary code       execution (bsc#1272765).

    Other updates and bugfixes:

    - Release 4.4.8
      * Various bug fixes to codecs
      * avcodec/magicyuv: Fix 1 line MEDIAN slices
      * avcodec/magicyuv: Expand the s->interlaced slice-height sanity check
      * avcodec/magicyuv: reject slice_height misaligned with chroma vshift

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
