CVE-2025-0835

Kernel heap corruption via double page release

Published Mar 24, 2025 · Updated Mar 24, 2025

Use-after-free in Imagination Technologies Graphics DDK 23.2 RTM through 24.2 RTM2 allows local users to corrupt kernel heap memory. _WrapExtMemReleasePages releases pages a second time when _FlushUMVirtualRange fails, leaving freed kernel heap memory subject to reuse. A non-privileged local process must issue crafted GPU system calls, exposing kernel confidentiality, integrity, and availability.
