CVE-2026-49745 Imagination Technologies CVE debrief
The CVE-2026-49745 vulnerability affects kernel software installed and running inside a Guest VM, which may post improper commands to the GPU Firmware, triggering a write of data outside the Guest's virtualized GPU memory. This vulnerability has a high CVSS score of 7.8 and could potentially allow for privilege escalation. Organizations using virtualized environments with Guest VMs and GPU acceleration should be aware of this vulnerability and take steps to mitigate it. The CVE record was published on 2026-07-24T09:16:24.897Z and has not been modified since then. Affected systems should be prioritized for patching.

Who should care
Organizations using virtualized environments with Guest VMs and GPU acceleration should be aware of this vulnerability and take steps to mitigate it. Affected operators, platforms, and security teams should prioritize patching and implement compensating controls to limit potential damage. Vulnerability management and security teams should review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance. They should also plan vendor-supported updates or mitigations through normal change control where exposure is confirmed. Additionally, they should review compensating controls for exposed systems while remediation is scheduled and verified, and check relevant monitoring, detection, and logs for exposed assets that need extra review. Finally, they should track exceptions, retest remediated assets, and close the item only after evidence is documented.
