CVE-2026-108094: Use After Free in Red Hat Red Hat Enterprise Linux 10
Description
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.

Technical Analysis
This vulnerability involves a use-after-free condition in mutter's handling of Wayland color-management ICC image descriptions. The flaw occurs when a malicious local Wayland client destroys a wp_image_description_v1 resource during an asynchronous ICC file read. Upon completion of the read, the compositor accesses and modifies freed memory, which can cause a crash and may allow execution of arbitrary code in the compositor process. The issue affects Red Hat Enterprise Linux 10 and has a CVSS 3.1 base score of 7.8, indicating high severity.
Potential Impact
Successful exploitation can crash the GNOME session and potentially allow a local attacker to execute arbitrary code within the compositor process. This could lead to privilege escalation or compromise of the graphical session on affected systems.
