Prior to version 7.1.0, `(*backend).CreateCustomVolumeFromBackup` in `internal/server/storage/backend.go` contains an unguarded `*time.Time` dereference on the `ExpiresAt` field of every volume-snapshot entry in an imported custom-volume backup. An authenticated user with `can_create_storage_volumes` permission on any project can crash the `incusd` daemon by uploading a backup tarball whose `volume_snapshots[*].expires_at` field is absent. This is a sibling-field variant of GHSA-r7w7-mmxr-47r9 (CVE-2026-40197). Commit `985a1dedf9f3e7ba729c93b654905ed510de25c2` added `if s == nil` at the top of the loop body, but did not guard the adjacent `*snapshot.ExpiresAt` deref 19 lines later. Every other consumer of `Config.VolumeSnapshots[i].ExpiresAt` 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.","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-xhqx-mgh3-3h7q"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-63974","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Aug 21, 2026, 2:10:34 PM","dateUpdated":"Aug 21, 2026, 9:44:23 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.
