Guest GPU memory disclosure via unchecked loop bounds
Published Jan 13, 2025 · Updated Jan 13, 2025
An out-of-bounds read in Imagination Technologies Graphics DDK 1.15 RTM through 24.2 RTM2 allows guest OS users to read beyond GPU memory. The firmware-log path accepts improper guest-kernel commands and advances an out-of-range pointer because its loop bounds are not checked. Exploitation requires kernel software running inside a guest VM that can submit crafted GPU firmware commands, exposing data outside that guest's virtualized 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.
