CVE-2026-45202 Imagination Technologies CVE debrief

Who should care

System administrators and users of Unknown Vendor software, particularly those using Imagination Technologies GPU drivers, should review and apply vendor patches or updates, monitor system logs for signs of memory leaks or corruption, and implement compensating controls to limit potential damage. Security teams should prioritize patching and verify affected product deployments.

Technical summary

The vulnerability occurs when software installed and run as a non-privileged user conducts GPU system calls, potentially causing GPU memory leaks and kernel heap corruption. This is due to memory free paths not maintaining state data of upgraded higher order allocations, which could lead to memory leaks or double free events. The vulnerability affects Imagination Technologies GPU drivers and could allow an attacker to cause memory leaks or kernel heap corruption. Defenders should prioritize patching and verify affected product deployments.

Defensive priority

Medium priority due to potential for memory leaks and kernel heap corruption

Recommended defensive actions

• Review and apply vendor patches or updates
• Monitor system logs for signs of memory leaks or corruption
• Implement compensating controls to limit potential damage
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Check relevant monitoring, detection, and logs for exposed assets that need extra review

Evidence notes
