{"id":"DEBIAN-CVE-2026-123876","details":"A flaw was found in the default seccomp profile used by Podman via containers-common. Deny rules for AF_VSOCK and NETLINK_AUDIT compared socket arguments with unmasked 64-bit equality. Because the kernel truncates those int arguments to 32 bits, setting upper bits can bypass the deny rules.","modified":"2026-11-07T23:00:06.673990776Z","published":"2026-11-06T18:18:05.410Z","upstream":["CVE-2026-123876"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-123876"}],"affected":[{"package":{"name":"podman","ecosystem":"Debian:13","purl":"pkg:deb/debian/podman?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.4.2+ds1-2","5.6.1+ds1-1","5.6.1+ds1-2","5.6.1+ds2-2","5.6.1+ds2-3","5.6.2+ds1-1","5.6.2+ds1-2","5.6.2+ds1-3","5.6.2+ds1-3+exp1","5.6.2+ds1-4","5.7.0+ds2-1","5.7.0+ds2-2","5.7.0+ds2-3","5.8.0+ds1-1","5.8.1+ds1-1","5.8.1+ds1-2","5.8.1+ds1-3","5.8.2+ds1-1","5.8.2+ds1-2","5.8.2+ds1-3","5.8.3+ds1-1","5.8.4+ds1-1","5.8.4+ds1-2","5.8.6+ds1-1","5.8.6+ds1-2","5.8.6+ds1-3","6.1.1+ds1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-123876.json"}},{"package":{"name":"podman","ecosystem":"Debian:14","purl":"pkg:deb/debian/podman?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.4.2+ds1-2","5.6.1+ds1-1","5.6.1+ds1-2","5.6.1+ds2-2","5.6.1+ds2-3","5.6.2+ds1-1","5.6.2+ds1-2","5.6.2+ds1-3","5.6.2+ds1-3+exp1","5.6.2+ds1-4","5.7.0+ds2-1","5.7.0+ds2-2","5.7.0+ds2-3","5.8.0+ds1-1","5.8.1+ds1-1","5.8.1+ds1-2","5.8.1+ds1-3","5.8.2+ds1-1","5.8.2+ds1-2","5.8.2+ds1-3","5.8.3+ds1-1","5.8.4+ds1-1","5.8.4+ds1-2","5.8.6+ds1-1","5.8.6+ds1-2","5.8.6+ds1-3","6.1.1+ds1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-123876.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N"}]}
