{"id":"DEBIAN-CVE-2026-88373","details":"libde265 commit 4d45a6b contains a NULL pointer dereference vulnerability in the NAL parsing path. When de265_push_NAL() is called with a zero-length NAL unit, the resulting NAL_unit may retain a NULL backing buffer, which is subsequently passed as the destination argument to memcpy() in NAL_unit::set_data(). Although the copy length is zero, this violates the nonnull requirement of memcpy() and results in undefined behavior, causing process termination in UBSan-instrumented builds and denial of service.","modified":"2026-09-26T09:00:17.908207328Z","published":"2026-09-24T17:17:07.197Z","upstream":["CVE-2026-88373"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-88373"}],"affected":[{"package":{"name":"libde265","ecosystem":"Debian:12","purl":"pkg:deb/debian/libde265?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.11-1","1.0.11-1+deb12u1","1.0.11-1+deb12u2","1.0.11-1+deb12u3","1.0.12-1","1.0.12-2","1.0.13-1","1.0.15-1","1.0.16-1","1.0.18-1","1.1.1-1","1.1.2-1","1.1.3-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88373.json"}},{"package":{"name":"libde265","ecosystem":"Debian:13","purl":"pkg:deb/debian/libde265?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.15-1","1.0.15-1+deb13u1","1.0.15-1+deb13u2","1.0.16-1","1.0.18-1","1.1.1-1","1.1.2-1","1.1.3-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88373.json"}},{"package":{"name":"libde265","ecosystem":"Debian:14","purl":"pkg:deb/debian/libde265?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.1.2-1"}]}],"versions":["1.0.15-1","1.0.16-1","1.0.18-1","1.1.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88373.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
