CVE-2026-16280 Imagination Technologies CVE debrief

Who should care

System administrators, security teams, and users of affected systems should be aware of this vulnerability and take necessary actions to mitigate it. Affected operators and platforms should review the vulnerability and implement compensating controls if necessary.

Technical summary

An integer overflow when calculating physical offsets for sparse PMRs may result in 32-bit truncation of address computations for PMRs larger than 4 GB. This can lead to incorrect GPU MMU mappings and may allow a non-privileged user to trigger access to unintended physical memory, resulting in memory corruption or information disclosure. The vulnerability affects GPU drivers and has a high impact on system security.

Defensive priority

High

Recommended defensive actions

• Apply the vendor's patch or update to fix the vulnerability
• Restrict access to affected systems and monitor for suspicious activity
• Perform regular security audits and vulnerability assessments
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
