Who should care

Users of GPU drivers from Imagination Technologies may be affected by this vulnerability. System administrators and security teams responsible for managing and securing systems that utilize these GPU drivers should assess their exposure and take necessary precautions.

Technical summary

The vulnerability occurs in the page freeing logic of the sparse memory implementation within the GPU driver from Imagination Technologies. When indexing pages larger than 4kB, incorrect buffer indexing leads to out-of-bounds (OOB) access. This could allow software installed and run as a non-privileged user to cause OOB kernel memory reads or writes through GPU API calls. The affected product is the GPU driver from Imagination Technologies, which may be used in various systems. Users of these GPU drivers should assess their exposure and take necessary precautions to prevent unauthorized access to sensitive kernel memory. To verify, defenders should check Imagination Technologies' official website for GPU driver updates and assess the potential impact on their systems. They should also review system logs for suspicious GPU API activity.

Defensive priority

High priority for users of affected GPU drivers

Recommended defensive actions

  • Inventory and assess GPU driver installations for potential exposure
  • Apply vendor patches or updates when available
  • Monitor system logs for suspicious GPU API activity
  • Consider compensating controls such as memory protection mechanisms
  • Review and update asset inventory to track affected systems
  • Implement monitoring and detection mechanisms for exposed assets
  • Track exceptions and retest remediated assets
