{"id":"JLSEC-2026-1174","summary":"FFmpeg versions 4.4 through 8.1.2 contain a double-free vulnerability in the NVIDIA NVDEC...","details":"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.","modified":"2026-08-07T13:43:39.189609512Z","published":"2026-08-07T13:27:45.313Z","upstream":["CVE-2026-64832","EUVD-2026-47756","GHSA-jc8j-9799-c943"],"database_specific":{"license":"CC-BY-4.0","sources":[{"modified":"2026-07-28T17:01:21.170Z","published":"2026-07-22T18:17:05.483Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-64832","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64832","database_specific":{"status":"Analyzed"},"id":"CVE-2026-64832","imported":"2026-08-07T05:41:14.513Z"},{"html_url":"https://github.com/advisories/GHSA-jc8j-9799-c943","id":"GHSA-jc8j-9799-c943","imported":"2026-08-07T05:42:30.216Z","modified":"2026-07-22T18:32:47Z","published":"2026-07-22T18:32:40Z","url":"https://api.github.com/advisories/GHSA-jc8j-9799-c943"},{"html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-47756","id":"EUVD-2026-47756","imported":"2026-08-07T05:41:15.760Z","modified":"2026-07-28T01:06:03Z","published":"2026-07-22T17:01:16Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-47756"}]},"references":[{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/commit/4c6217477fc64305055b37d9d1d0d76d30e37f97"},{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/23664"},{"type":"WEB","url":"https://github.com/advisories/GHSA-jc8j-9799-c943"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64832"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/ffmpeg-double-free-in-nvdec-hardware-decoder-via-nvdec-c"}],"affected":[{"package":{"name":"FFMPEG_jll","ecosystem":"Julia","purl":"pkg:julia/FFMPEG_jll?uuid=b22a6f82-2f65-5046-a5b2-351ab43fb4e5"},"ranges":[{"type":"SEMVER","events":[{"introduced":"4.4.0+0"},{"fixed":"9.0.0+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-1174.json"}},{"package":{"name":"FFMPEG_nogpl_jll","ecosystem":"Julia","purl":"pkg:julia/FFMPEG_nogpl_jll?uuid=a6892c6b-5768-548c-b024-ff8dabf482c5"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"9.0.0+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-1174.json"}},{"package":{"name":"FFplay_jll","ecosystem":"Julia","purl":"pkg:julia/FFplay_jll?uuid=c4dce911-e170-5107-8314-c7bdc6785395"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-1174.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
