Cross-boundary memory write via unchecked firmware offset
Published Jan 13, 2025 · Updated Jan 13, 2025
An out-of-bounds write in Imagination Technologies Graphics DDK 24.2 RTM2 and earlier allows guest OS users to write beyond guest GPU memory. The rgxfw_kernel_CMD_DISABLE_ZSSTORE firmware command uses ui32WriteOffsetOfDisableZSStore without sufficient bounds validation when accessing memory shared with the guest. Kernel software must run inside a guest VM and reach that shared memory; public sources do not identify the overwritten target or a resulting code-execution path.

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.
