Cross-world data disclosure via residual GPU registers
Published Jan 13, 2026 · Updated Jan 13, 2026
Information disclosure in Imagination Technologies Graphics DDK 25.2 RTM and earlier allows remote attackers to read secure GPU register data. The driver leaves intermediate register values from a secure workload available to later workloads scheduled by non-secure applications instead of applying the vendor's added leak protection. Exploitation requires a non-secure application to schedule a workload on the same platform after a secure workload, exposing register contents but no reported service interruption.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=1.15 RTM
- Affected versionversion=1.17 RTM
- Affected versionversion=1.18 RTM
- Affected versionversion=23.2 RTM <=25.2 RTM
