Virtualization escape via out-of-range firmware pointer
Published Apr 18, 2025 · Updated Apr 21, 2025
Out-of-bounds write in Imagination Technologies Graphics DDK 1.15 RTM through 24.3 RTM allows guest OS users to escape GPU memory isolation. In rgxfw_hwperf_get_packet_buffer, a guest-controlled out-of-range pointer offset directs GPU firmware writes beyond the guest's virtualized allocation. Kernel software must already be installed and running in a guest VM, and exploitation can corrupt memory outside that guest's GPU allocation.

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.
