Incus is a system container and virtual machine manager. Prior to version 7.1.0,
(*backend).CreateInstanceFromBackupininternal/server/storage/backend.gocontains 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 ofGHSA-fwj8-62r8-8p8m,GHSA-r7w7-mmxr-47r9, andGHSA-x5r6-jr56-89pv(all assigned 2026-05-04). Those patches added guards on adjacent fields of the samebackup/config.Configstruct; theVolumefield on the instance-import path was missed. Version 7.1.0 contains an updated patch. - References
