{"apiVersion":"1.0","identifier":"CVE-2026-75142","description":"FFmpeg before commit 9d786e4 contains a stack buffer overflow in the MPEG-PS muxer (libavformat/mpegenc.c). When muxing input with more streams than the muxer-s fixed-size stack buffer accommodates, the buffer is overflowed. A crafted input with an excessive number of streams triggers the overflow during MPEG-PS muxing.","publishedAt":"2026-08-19T17:21:12","lastModifiedAt":"2026-08-27T17:19:54","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-75142","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","epssProbability":0.00137,"riskScore":0.79,"affectedProduct":"FFmpeg","affectedVersions":"unknown","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-75142","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-75142","en":"https://www.redsauce.net/en/cves/CVE-2026-75142","fr":"https://www.redsauce.net/fr/cves/CVE-2026-75142","pt":"https://www.redsauce.net/pt/cves/CVE-2026-75142","de":"https://www.redsauce.net/de/cves/CVE-2026-75142","sk":"https://www.redsauce.net/sk/cves/CVE-2026-75142","el":"https://www.redsauce.net/el/cves/CVE-2026-75142"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-75142"}}
