Arbitrary physical-memory write via cross-requestor GPU buffers
Published May 1, 2026 · Updated May 1, 2026
Memory corruption in Imagination Technologies Graphics DDK through 25.3 RTM allows local users to overwrite arbitrary physical memory. Cache-resident physical-memory buffers in the DDK kernel module remain writable by other GPU requestors, so crafted GPU system calls redirect writes beyond GPU-owned pages. A non-privileged local account that can submit GPU work is sufficient, and corruption of kernel or driver pages can alter platform behavior.

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.
- Affected versionversion=1.18 RTM
- Affected versionversion=23.2 RTM
- Affected versionversion=24.1 RTM <=24.2 RTM
- Affected versionversion=25.1 RTM <=25.3 RTM
