Cross-boundary read and write via shared heap pointer
Published May 17, 2025 · Updated May 19, 2025
Out-of-bounds access in Imagination Technologies Graphics DDK 1.15 RTM through 24.3 RTM allows guest OS users to read or write GPU memory. In VZ/TEE setups, an out-of-range pointer offset reaches the shared KMD/firmware heap without confining the resulting access to the guest's virtualized GPU allocation. Reachability requires kernel software inside a Guest VM with shared GPU-firmware memory; the bounded consequence is cross-boundary data disclosure or modification.

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.
