{"cve":"CVE-2026-47753","nvd":{"published":"2026-08-21T15:16:40.067","modified":"2026-10-15T19:10:00.173","status":"Deferred","description":"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.","cvss_v4":{"vector":"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","score":4.4},"cvss_v3":null,"cwes":["CWE-476"],"references":["https://github.com/lxc/incus/commit/98e64f0a6fcfdc9676eea0246418d490c53297bf","https://github.com/lxc/incus/security/advisories/GHSA-8g7m-96c8-8wwc","https://github.com/lxc/incus/security/advisories/GHSA-8g7m-96c8-8wwc"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-47753","score":0.00152,"percentile":0.04318,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-8g7m-96c8-8wwc","url":"https://osv.dev/vulnerability/GHSA-8g7m-96c8-8wwc","summary":"Incus has a Nil-Pointer Dereference Panic via Instance Backup Import (volume omitted)","modified":"2026-06-25T19:56:32.862353946Z","packages":[{"ecosystem":"Go","name":"github.com/lxc/incus/v7","purl":"pkg:golang/github.com/lxc/incus/v7","ranges":["<7.1.0"],"fixed":["7.1.0"]}]},{"id":"GO-2026-5252","url":"https://osv.dev/vulnerability/GO-2026-5252","summary":"Incus has a Nil-Pointer Dereference Panic via Instance Backup Import (volume omitted) in github.com/lxc/incus","modified":"2026-06-25T19:45:21.744304544Z","packages":[{"ecosystem":"Go","name":"github.com/lxc/incus","purl":"pkg:golang/github.com/lxc/incus","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/lxc/incus/v6","purl":"pkg:golang/github.com/lxc/incus/v6","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/lxc/incus/v7","purl":"pkg:golang/github.com/lxc/incus/v7","ranges":["<7.1.0"],"fixed":["7.1.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
