CVE-2024-46972

Kernel exceptions via export-fence reference-count overflow

Published Dec 28, 2024 · Updated Mar 13, 2025

Use-after-free in Imagination Technologies Graphics DDK 24.1 RTM allows local users to trigger kernel exceptions via improper GPU system calls. The pvr_sync_rollback_export_fence path improperly updates a fence reference count until it overflows, leaving kernel code to use a freed object. A non-privileged local process with access to the PowerVR GPU driver is sufficient; the vendor reports kernel exceptions but does not detail further exploit outcomes.
