LOWPre-NVD 2.12.1
EchelonGraph scoreLOW confidence

This low-severity CVE scores 2.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Incus is a system container and virtual machine manager. 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.
