{"apiVersion":"1.0","identifier":"CVE-2026-48754","description":"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.","publishedAt":"2026-08-21T15:16:40","lastModifiedAt":"2026-08-26T18:16:34","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-48754","cvssScore":2.1,"cvssVector":"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/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00226,"riskScore":0.21,"affectedProduct":"Incus","affectedVersions":"<7.1.0","vulnerabilityType":"Critical software","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-48754","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-48754","en":"https://www.redsauce.net/en/cves/CVE-2026-48754","fr":"https://www.redsauce.net/fr/cves/CVE-2026-48754","pt":"https://www.redsauce.net/pt/cves/CVE-2026-48754","de":"https://www.redsauce.net/de/cves/CVE-2026-48754","sk":"https://www.redsauce.net/sk/cves/CVE-2026-48754","el":"https://www.redsauce.net/el/cves/CVE-2026-48754"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-48754"}}
