CVE-2026-108094
Mutter: mutter: client-triggered use-after-free in wayland color-management icc image description path
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.
Fixes and workarounds
Workaround
Do not run untrusted applications in the affected Wayland session. Limit Wayland socket access for untrusted clients.
