Incus is a system container and virtual machine manager. Prior to version 7.1.0, in contains an unguarded dereference on the field of every volume-snapshot entry in an imported custom-volume backup. An authenticated user with permission on any project can crash the daemon by uploading a backup tarball whose field is absent. This is a sibling-field variant of GHSA-r7w7-mmxr-47r9 (CVE-2026-40197). Commit added at the top of the loop body, but did not guard the adjacent deref 19 lines later. Every other consumer of in this same file already gates the deref with a nil-check — the asymmetric guard is the bug. Version 7.1.0 contains an updated patch.
No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
