Imagination Technologies GPU Driver Privilege Escalation Vulnerability via Firmware State Override

A vulnerability exists in the Imagination Technologies GPU driver that allows software running in a Guest VM to manipulate the Firmware's connection state, potentially leading to unauthorized access to the GPU. This issue arises from improper handling of virtualized GPU memory, enabling guest applications to override Firmware states and access GPU resources inappropriately.

Impact

Exploitation of this vulnerability could result in unauthorized access to GPU resources, allowing for manipulation of graphics processing tasks and potentially disrupting normal operations or causing system instability.

Remediation

Users can update to the latest version of the Imagination Technologies GPU driver, which includes patches to address this vulnerability by preventing unauthorized access to the GPU from within a Guest VM.
