CVE-2026-49745 Details
Description
Kernel software installed and running inside a Guest VM may post improper commands to the GPU Firmware to trigger a write of data outside the Guest's virtualised GPU memory. Software installed and run under a Guest VM can send commands to the GPU which result in out of bounds memory accesses. These can be used to escalate privileges.
A vulnerability exists in the GPU driver component of Imagination Technologies that allows for privilege escalation. This issue arises from improper handling of commands sent to the GPU firmware, which can lead to out-of-bounds memory accesses. Software running in a guest virtual machine can exploit this vulnerability by sending malicious commands that cause data to be written outside the allocated GPU memory, potentially overwriting critical information and escalating privileges.
Users can update to the latest version of the Imagination Technologies GPU driver, which includes patches for this vulnerability. Instructions for updating the driver can be found on the Imagination Technologies website or through the Imagination Technologies support representative.
