Cross-guest GPU memory write via arbitrary register mapping
Published Feb 22, 2025 · Updated Feb 24, 2025
Out-of-bounds write in Imagination Technologies Graphics DDK 1.15 RTM through 24.3 RTM allows guest OS users to modify another guest's GPU memory. The rgxfw_write_robustness_buffer firmware path permits an arbitrary category-register set mapping from shared memory without confining the write to the calling guest's virtualized GPU address space. Exploitation requires kernel software inside a GPU-enabled guest VM and can corrupt another guest's GPU-resident data; no host-memory or availability impact is reported.

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.
