CVE-2026-49745 · Severity: info · CVSS 0 · Published 2026-07-24

A vulnerability in the Imagination Technologies Graphics DDK allows software running inside a guest virtual machine to send malicious commands to the GPU firmware. This can result in the GPU writing data outside of its assigned memory area, potentially allowing an attacker to gain higher privileges on the system. This could lead to unauthorized access to data or control over the host environment.
