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.","state":0,"publishedAt":"2026-08-21T14:36:16.011+00:00","modifiedAt":"2026-08-26T17:26:19.767+00:00","affected":[{"ecosystem":"Vendor product","name":"incus","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"lxc\",\n                    \"product\": \"incus\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 7.1.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P","score":2.1,"severity":"LOW"}],"references":["https://github.com/lxc/incus/security/advisories/GHSA-4xg6-52mh-fpw8"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-48754","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-48754","identifiers":["CVE-2026-48754"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
