  "description": "Incus is a system container and virtual machine manager. Prior to version 7.1.0, \u0060(*backend).CreateCustomVolumeFromBackup\u0060 in \u0060internal/server/storage/backend.go\u0060 contains an unguarded \u0060*time.Time\u0060 dereference on the \u0060ExpiresAt\u0060 field of every volume-snapshot entry in an imported custom-volume backup. An authenticated user with \u0060can_create_storage_volumes\u0060 permission on any project can crash the \u0060incusd\u0060 daemon by uploading a backup tarball whose \u0060volume_snapshots[*].expires_at\u0060 field is absent. This is a sibling-field variant of GHSA-r7w7-mmxr-47r9 (CVE-2026-40197). Commit \u0060985a1dedf9f3e7ba729c93b654905ed510de25c2\u0060 added \u0060if s == nil\u0060 at the top of the loop body, but did not guard the adjacent \u0060*snapshot.ExpiresAt\u0060 deref 19 lines later. Every other consumer of \u0060Config.VolumeSnapshots[i].ExpiresAt\u0060 in this same file already gates the deref with a nil-check \u2014 the asymmetric guard is the bug. Version 7.1.0 contains an updated patch.",
