Kernel Vulnerability in Imagination Technologies' GPU Driver

CVE-2026-45203

What is CVE-2026-45203?

A vulnerability exists in the GPU driver of Imagination Technologies, specifically in the handling of memory commands. Malicious software could exploit a time-of-check to time-of-use (TOCTOU) flaw, allowing alterations to memory values after the driver's firmware validation has occurred, but before those values are used by the host kernel. This can lead to unauthorized memory writes, posing a risk to the integrity and stability of the system. Prompt attention and remediation are necessary to protect systems utilizing affected versions of the driver.
