{"id":"DEBIAN-CVE-2026-88386","details":"libsndfile 1.2.2 contains a misaligned memory access issue in psf_binheader_readf() while parsing WAV fmt chunks. A specially crafted WAV file can cause the function to cast an unaligned destination address to unsigned int * and perform a 4-byte store. This results in undefined behavior leading to denial of service.","modified":"2026-09-26T09:00:10.115527498Z","published":"2026-09-24T21:18:57.003Z","upstream":["CVE-2026-88386"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-88386"}],"affected":[{"package":{"name":"libsndfile","ecosystem":"Debian:12","purl":"pkg:deb/debian/libsndfile?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.0-1","1.2.0-1+deb12u1","1.2.2-1","1.2.2-1+hurd.1","1.2.2-1+hurd.2","1.2.2-1+hurd.3","1.2.2-2","1.2.2-3","1.2.2-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88386.json"}},{"package":{"name":"libsndfile","ecosystem":"Debian:13","purl":"pkg:deb/debian/libsndfile?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.2-2","1.2.2-2+deb13u1","1.2.2-3","1.2.2-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88386.json"}},{"package":{"name":"libsndfile","ecosystem":"Debian:14","purl":"pkg:deb/debian/libsndfile?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.2-2","1.2.2-3","1.2.2-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88386.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"}]}
