Detailsinfo

A vulnerability was found in Imagination Graphics DDK up to 26.1 RTM1. It has been rated as very critical. Affected by this issue is an unknown function of the component GPU Firmware. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Kernel software from a non-secure operating system on a platform with Trusted Execution Environment support, may cause GPU Firmware to boot up using data from non-secure memory. The GPU thread of control (Firmware) uses a pointer from non-secure memory belonging to the Rich Execution Environment (REE) when saving or retrieving internal data between the tightly coupled private memory to main memory. An attacker with control over the REE kernel may modify the pointer value, corrupting the data used by the GPU Firmware.

The advisory is available at imaginationtech.com. This vulnerability is handled as CVE-2026-45198 since 05/11/2026. The exploitation is known to be easy. Local access is required to approach this attack. Additional levels of successful authentication are necessary for exploitation. The technical details are unknown and an exploit is not available.
