{"id":"DEBIAN-CVE-2026-62313","details":"Incus is a system container and virtual machine manager. Prior to version 7.3.0, project-level enforcement of `restricted.containers.privilege=isolated` can be trivially bypassed, allowing a user to create a non-isolated (shared host idmap) container in a project that is configured to forbid them. The restriction only rejects an explicitly set `security.idmap.isolated=false` (or empty) and fails to enforce anything when the key is omitted entirely. Because an unset `security.idmap.isolated` defaults to `false` (non-isolation), a user simply leaves the key out and obtains exactly the container state the restriction is meant to forbid. This defeats the tenant-isolation guarantee the restriction exists to provide. Containers in the project share the host uid/gid map instead of receiving unique, non-overlapping ranges, weakening the isolation boundary between co-tenant containers and the host. Version 7.3.0 patches the issue.","modified":"2026-09-19T22:47:26.520508084Z","published":"2026-08-21T15:16:45.867Z","upstream":["CVE-2026-62313"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-62313"}],"affected":[{"package":{"name":"incus","ecosystem":"Debian:13","purl":"pkg:deb/debian/incus?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.4-2+deb13u9"}]}],"versions":["6.0.4-2","6.0.4-2+deb13u1","6.0.4-2+deb13u1~bpo12+1","6.0.4-2+deb13u2","6.0.4-2+deb13u2~bpo12+1","6.0.4-2+deb13u3","6.0.4-2+deb13u3~bpo12+1","6.0.4-2+deb13u4","6.0.4-2+deb13u4~bpo12+1","6.0.4-2+deb13u5","6.0.4-2+deb13u5~bpo12+1","6.0.4-2+deb13u6","6.0.4-2+deb13u6~bpo12+1","6.0.4-2+deb13u7","6.0.4-2+deb13u7~bpo12+1","6.0.4-2+deb13u8"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-62313.json"}},{"package":{"name":"incus","ecosystem":"Debian:14","purl":"pkg:deb/debian/incus?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.0.1-2"}]}],"versions":["6.0.4-2","6.0.4-3","6.0.5-1","6.0.5-2","6.0.5-3","6.0.5-4","6.0.5-5","6.0.5-6","6.0.5-7","6.0.5-8","6.0.6-1","6.0.6-2","6.0.6-3","6.14.0-1~exp1","6.15.0-1~exp1","6.16.0-1~exp1","6.17.0-1~exp1","6.20.0-1~exp1","6.21.0-1~exp1","6.22.0-1~exp1","6.23.0-1~exp1","7.0.0-1","7.0.0-1~bpo13+1","7.0.0-2","7.0.0-2~bpo13+1","7.0.0-3","7.0.0-4","7.0.0-5","7.0.0-5~bpo13+1","7.0.1-1","7.0.1-1~bpo13+1","7.0.1-2~bpo13+1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-62313.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L"}]}
