{"id":"DEBIAN-CVE-2025-10256","details":"A NULL pointer dereference vulnerability exists in FFmpeg’s Firequalizer filter (libavfilter/af_firequalizer.c) due to a missing check on the return value of av_malloc_array() in the config_input() function. An attacker could exploit this by tricking a victim into processing a crafted media file with the Firequalizer filter enabled, causing the application to dereference a NULL pointer and crash, leading to denial of service.","modified":"2026-09-01T16:06:07.852464374Z","published":"2026-02-18T21:16:20.183Z","upstream":["CVE-2025-10256"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-10256"}],"affected":[{"package":{"name":"ffmpeg","ecosystem":"Debian:12","purl":"pkg:deb/debian/ffmpeg?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["7:5.1.3-1","7:5.1.3-2","7:5.1.4-0+deb12u1","7:5.1.5-0+deb12u1","7:5.1.6-0+deb12u1","7:5.1.7-0+deb12u1","7:5.1.8-0+deb12u1","7:5.1.9-0+deb12u1","7:6.0-1","7:6.0-2","7:6.0-3","7:6.0-4","7:6.0-5","7:6.0-6","7:6.0-7","7:6.0-8","7:6.0-9","7:6.1-1","7:6.1-2","7:6.1-3","7:6.1-4","7:6.1-5","7:6.1.1-1","7:6.1.1-2","7:6.1.1-3","7:6.1.1-4","7:6.1.1-5","7:7.0-1","7:7.0.1-1","7:7.0.1-2","7:7.0.1-3","7:7.0.1-4","7:7.0.1-5","7:7.0.2-1","7:7.0.2-2","7:7.0.2-3","7:7.1-1","7:7.1-2","7:7.1-3","7:7.1-4","7:7.1.1-1","7:7.1.2-1","7:7.1.3-1","7:8.0-1","7:8.0-2","7:8.0.1-1","7:8.0.1-2","7:8.0.1-3","7:8.1-1","7:8.1-2","7:8.1-3","7:8.1.1-1","7:8.1.1-2","7:8.1.1-3","7:8.1.1-4","7:8.1.2-1","7:8.1.2-2","7:9.0-1","7:9.0.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-10256.json"}},{"package":{"name":"ffmpeg","ecosystem":"Debian:13","purl":"pkg:deb/debian/ffmpeg?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7:7.1.2-0+deb13u1"}]}],"versions":["7:7.1.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-10256.json"}},{"package":{"name":"ffmpeg","ecosystem":"Debian:14","purl":"pkg:deb/debian/ffmpeg?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7:7.1.2-1"}]}],"versions":["7:7.1.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-10256.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
