{"id":"CVE-2026-47753","summary":"Incus has a Nil-Pointer Dereference Panic via Instance Backup Import (volume omitted)","details":"Incus is a system container and virtual machine manager. Prior to version 7.1.0, `(*backend).CreateInstanceFromBackup` in `internal/server/storage/backend.go` contains a nil-pointer dereference that an authenticated user with permission to create instances in any project can trigger remotely by uploading a crafted backup tarball. The Incus daemon panics and the process crashes, causing denial of service to every project on that cluster member. This is a sibling of `GHSA-fwj8-62r8-8p8m`, `GHSA-r7w7-mmxr-47r9`, and `GHSA-x5r6-jr56-89pv` (all assigned 2026-05-04). Those patches added guards on adjacent fields of the same `backup/config.Config` struct; the `Volume` field on the instance-import path was missed. Version 7.1.0 contains an updated patch.","aliases":["GHSA-8g7m-96c8-8wwc","GO-2026-5252"],"modified":"2026-08-23T03:53:38.347886546Z","published":"2026-08-21T14:14:12.280Z","related":["openSUSE-SU-2026:21483-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-476"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47753.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47753.json"},{"type":"ADVISORY","url":"https://github.com/lxc/incus/security/advisories/GHSA-8g7m-96c8-8wwc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47753"},{"type":"FIX","url":"https://github.com/lxc/incus/commit/98e64f0a6fcfdc9676eea0246418d490c53297bf"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/lxc/incus","events":[{"introduced":"0"},{"fixed":"98e64f0a6fcfdc9676eea0246418d490c53297bf"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"7.1.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v7.0.0","v6.23.0","v6.22.0","v6.21.0","v6.20.0","v6.19.1","v6.19.0","v6.18.0","v6.17.0","v6.16.0","v6.14.0","v6.15.0","v6.13.0","v6.12.0","v6.11.0","v6.10.1","v6.10.0","v6.9.0","v6.8.0","v6.7.0","v6.6.0","v6.5.0","v6.4.0","v6.3.0","v6.2.0","v6.0.0","v6.1.0","v0.7.0","v0.6.0","v0.5.1","v0.5.0","v0.4.0","v0.3.0","v0.2.0","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-47753.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U"}]}
