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":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD 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":null}],"references":["https://github.com/lxc/incus/security/advisories/GHSA-4xg6-52mh-fpw8"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-63981","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Aug 21, 2026, 2:36:16 PM","dateUpdated":"Aug 26, 2026, 5:26:19 PM"},"relatedAdvisories":[{"id":"openSUSE-SU-2026:11651-1","title":"incus-7.4-1.1 on GA media","vulnerabilityIds":["CVE-2026-39402","CVE-2026-47753","CVE-2026-48749","CVE-2026-48750","CVE-2026-48751","CVE-2026-48752","CVE-2026-48753","CVE-2026-48754","CVE-2026-48755","CVE-2026-48756","CVE-2026-48769","CVE-2026-55621","CVE-2026-55622","CVE-2026-62313","CVE-2026-62867","CVE-2026-62940","CVE-2026-62941","CVE-2026-63125","CVE-2026-63343","CVE-2026-81500","CVE-2026-81501"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
