# CVE-2026-108094: Mutter: mutter: client-triggered use-after-free in wayland color-management icc image description path

Status: published. Published: 2026-10-12. Updated: 2026-11-04.

A use-after-free flaw was found in mutter in the Wayland color-management ICC image-description path. A local attacker who can run a malicious Wayland client can destroy a wp_image_description_v1 resource while an asynchronous ICC file read is still in progress. When the read completes, the compositor uses the freed wl_resource, writes into freed memory, and frees a pointer derived from that memory. This can crash the GNOME session and may allow arbitrary code execution within the compositor process.

## Remediation

- workaround: Do not run untrusted applications in the affected Wayland session. Limit Wayland socket access for untrusted clients. (source: CNA: redhat)
