Kernel memory corruption via writable Information Page
Published Jan 24, 2023 · Updated Apr 2, 2025
Out-of-bounds write in Imagination Technologies PowerVR GPU drivers before DDK 1.18 allows local users to corrupt kernel memory. The cache subsystem's Information Page, intended to accept writes only from the GPU driver, incorrectly permits a user-space process to write arbitrary data. Low-privileged local code on an affected Android SoC is required, and the documented consequence is memory corruption rather than disclosure or service interruption.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
