Published Aug 21, 2026 · updated Oct 15, 2026

Incus is a system container and virtual machine manager. Prior to version 7.1.0, in contains a cluster of unguarded pointer derefs on every dependent-volume entry's , , and sub-fields. An authenticated user with permission on any project can crash the daemon by uploading an instance backup tarball whose block contains a nil snapshot pointer (or omits / ). This is a sibling-field variant of the 2026-05-04 batch fix ("Properly check dependent volumes on import"). That commit added at the top of the outer loop, but did not guard the four sub-pointer fields the loop body dereferences naked. Version 7.1.0 contains an updated patch.
