CVE-2026-62313
Description
A flaw was found in Incus, a system container and virtual machine manager. A user within a project configured to forbid non-isolated containers can bypass this restriction by omitting a specific security setting (security.idmap.isolated). This allows the creation of containers that share the host's user and group ID map, rather than receiving unique, non-overlapping ranges. Consequently, the isolation boundary between co-tenant containers and the host is weakened, potentially leading to unauthorized access or information disclosure within the shared environment.
