The packetizer copies an input-derived data unit or fragment size into a fixed-size buffer without an upper bound check, causing a heap buffer overflow when the crafted input is packetized for RTP output.","state":0,"publishedAt":"2026-08-19T16:26:53.987+00:00","modifiedAt":"2026-10-27T10:14:31.556+00:00","affected":[{"ecosystem":"Vendor product","name":"FFmpeg","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"FFmpeg\",\n                    \"product\": \"FFmpeg\",\n                    \"repo\": \"https://code.ffmpeg.org/FFmpeg/FFmpeg\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"1cdeb3c4e7f1f8566d846b9b451e01c376398818\",\n                            \"versionType\": \"git\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:github/FFmpeg/FFmpeg\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.5,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/24091","https://code.ffmpeg.org/FFmpeg/FFmpeg/commit/1cdeb3c4e7f1f8566d846b9b451e01c376398818","https://www.vulncheck.com/advisories/ffmpeg-heap-buffer-overflow-in-vc-2-dirac-rtp-packetizer"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-75144","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-75144","identifiers":["CVE-2026-75144"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
