Prior to version 7.1.0, `(*backend).createDependentVolumesFromBackup` in `internal/server/storage/backend.go` contains a cluster of unguarded pointer derefs on every dependent-volume entry's `VolumeSnapshots[i]`, `Volume`, and `Pool` sub-fields. An authenticated user with `can_create_instances` permission on any project can crash the `incusd` daemon by uploading an instance backup tarball whose `dependent_volumes[*]` block contains a nil snapshot pointer (or omits `volume:` / `pool:`). This is a sibling-field variant of the 2026-05-04 batch fix `d768f81c0a1d985f35ae56219519822b080bf5e3` (\"Properly check dependent volumes on import\"). That commit added `if disk == nil` 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."}],"source":{"advisory":"GHSA-4xg6-52mh-fpw8","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/lxc/incus/security/advisories/GHSA-4xg6-52mh-fpw8","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-26T17:25:43.772920Z","id":"CVE-2026-48754","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-26T17:26:19.767Z"}}]}}
