1 security issue in trixie high

There is 1 open security issue in trixie.

1 important issue:

CVE-2026-108094: 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.
