CVE-2024-12837

Kernel heap corruption via checkpoint-array double free

Published Mar 7, 2025 · Updated Mar 7, 2025

Use-after-free in Imagination Technologies Graphics DDK 1.15 RTM through 24.3 RTM allows local users to corrupt kernel heap memory. The apsFenceSyncCheckpoints array is allocated with an arbitrary size and is freed twice by the kernel module after improper GPU system calls. Execution requires non-privileged local software able to issue GPU system calls, and the documented consequence is kernel heap corruption.
