Out-of-guest GPU memory write via shared pointer
Published Feb 22, 2025 · Updated Mar 18, 2025
Out-of-bounds write in Graphics DDK 1.15 RTM through 24.3 RTM allows guest OS users to corrupt GPU memory outside their VM. The rgxfw_pcset_ungrab firmware path uses psFWMemContext->uiPageCatBaseRegSet from GPU-firmware-shared memory without confining the resulting write to the guest's virtualized GPU allocation. Kernel software must run inside a guest VM and access memory shared with GPU firmware; the published consequence is limited to out-of-guest GPU-memory writes.

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.
