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.
