CVE-2026-45199: CWE-823: Use of Out-of-range Pointer Offset (4.16) in Imagination Technologies Graphics DDK
CVE-2026-45199 is a vulnerability in Imagination Technologies Graphics DDK where kernel software running inside a Guest VM can issue commands to the GPU firmware that cause writes outside the Guest's virtualized GPU memory. This out-of-bounds memory access can be exploited to escalate privileges within the virtualized environment.
AI Analysis
Technical Summary
The vulnerability involves improper handling of pointer offsets in the GPU firmware when processing commands from kernel software inside a Guest VM. Specifically, commands can trigger writes outside the allocated virtual GPU memory boundaries, leading to potential privilege escalation. This is classified under CWE-823: Use of Out-of-range Pointer Offset. No CVSS score or patch information is currently available.
Potential Impact
An attacker with the ability to run kernel software inside a Guest VM can exploit this flaw to perform out-of-bounds memory writes to the GPU firmware. This can lead to privilege escalation within the virtualized environment, potentially compromising the isolation between the Guest VM and the host or other VMs.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict untrusted code execution within Guest VMs and monitor for suspicious GPU command activity if possible.
