{"id":"CVE-2026-47753","aliases":["GHSA-8g7m-96c8-8wwc","GO-2026-5252"],"url":"https://o3.security/vulnerability/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.","published":"2026-08-21T14:14:12.280Z","modified":"2026-09-01T09:40:53.222888309Z","cvss":null,"epss":{"score":0.00141,"percentile":0.03673,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/lxc/incus/v7","fixedVersion":"7.1.0"}],"fix":{"url":"https://github.com/lxc/incus/commit/98e64f0a6fcfdc9676eea0246418d490c53297bf","label":"lxc/incus@98e64f0"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-01T09:40:53.222888309Z"}}
