Attackers can supply a crafted AIFF-C file that overwrites roughly 1 KB of adjacent stack memory when decoded, causing crashes or potential code execution.","published":"2026-11-05T15:11:47.851Z","modified":"2026-11-06T01:05:59.870943540Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/libsdl-org/SDL_mixer/commit/34486847a607540ce9ef5fbe20979c7140bf8c82","label":"libsdl-org/SDL_mixer@3448684"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/122xxx/CVE-2026-122329.json"},{"type":"PACKAGE","url":"https://github.com/libsdl-org/SDL_mixer"},{"type":"ARTICLE","url":"https://github.com/libsdl-org/SDL_mixer/blob/release-3.2.4/src/decoder_aiff.c#L535-536"},{"type":"ARTICLE","url":"https://github.com/libsdl-org/SDL_mixer/blob/release-3.2.4/src/decoder_aiff.c#L86-97"},{"type":"FIX","url":"https://github.com/libsdl-org/SDL_mixer/commit/34486847a607540ce9ef5fbe20979c7140bf8c82"},{"type":"REPORT","url":"https://github.com/libsdl-org/SDL_mixer/issues/907"},{"type":"ADVISORY","url":"https://hackmd.io/@haindpwn/sdl-mixer-fetchxlaw-stack-overflow"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-122329"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/sdl-mixer-3.1.2-through-3.2.4-stack-based-buffer-overflow-via-fetchxlaw-in-aiff-decoder"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-11-06T01:05:59.870943540Z"}}
