CVE-2024-46973

Kernel exceptions via psServerMMUContext use-after-free

Published Dec 28, 2024 · Updated Dec 28, 2024

Use-after-free in Imagination Technologies Graphics DDK 1.15 RTM through 24.2 RTM2 allows local users to trigger kernel exceptions. Reference-count mismanagement in psServerMMUContext frees a kernel object while GPU system calls can still reference it. Execution requires non-privileged local software able to issue crafted GPU system calls, exposing the kernel to memory compromise or service interruption.
