Investigated deeply (this session): the non-FUSE `chown` copy-up produces `upper/file` owned by **uid 1000, not root** here, so it doesn't escalate — the CVE needs the FUSE-reported-uid-0 lower. But **overlay refuses a userns-mounted FUSE lowerdir with `ENOSYS`** (plain overlay-in-userns works; FUSE-lower does not). A working port must mount FUSE in the **init ns** via the setuid `fusermount` helper (implement its fd-passing unix-socket protocol, or link libfuse), then overlay in the userns. A raw `/dev/fuse` server was written and reverted (hit the overlay-on-userns-FUSE `ENOSYS`). Substantial dedicated port. | +| `sudoedit_editor` | CVE-2023-22809 | Ubuntu 22.04.0 / sudo 1.9.9 | vulnerable sudo version + sudoers `sudoedit` grant present; module returns `EXPLOIT_FAIL` — the `SUDO_EDITOR`/`--` arg-injection reaches sudoedit's writable-dir guard.
