Kernel Module Vulnerability in Imagination Technologies GPU Driver

CVE-2026-22163

What is CVE-2026-22163?

This vulnerability allows attackers to exploit the DDK kernel module's IOCTL interface, which can be misused for unauthorized memory access. Due to the lack of synchronization in accessing shared resources, potential adversaries may hijack GPU operations to write to arbitrary physical memory pages, leading to severe security implications. This situation emphasizes the critical need for proper access controls and synchronization mechanisms within driver architectures.
