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.
