incus: Incus is a system container and virtual machine manager
CVE-2026-63343 is fixed in incus on 1 platform, first by DEBIAN-CVE-2026-63343, released August 1, 2026. It is not reported as exploited. Patch Radar priority: Urgent.
Incus is a system container and virtual machine manager. Prior to version 7.3.0, a malicious image containing a `metadata.yaml` symlink pointing to an arbitrary host path allows an authenticated Incus user to read or overwrite any file on the host as root via the instance metadata API. The `exec-output` and `templates/` paths were patched in a prior release using `Lstat` rejection and `os.OpenRoot` confinement; `metadata.yaml` was not included in either patch and remains exploitable. Version 7.3.0 patches the issue.
