Intermediate register values of secure workloads can be exfiltrated in workloads scheduled from applications running in the non-secure environment of a platform.
AnalysisAI
A hardware vulnerability allows exfiltration of intermediate register values from secure workloads running in ARM TrustZone or similar TEE environments. Non-secure applications can read secure-world register contents.
Technical ContextAI
Intermediate register values from secure workloads are accessible from the non-secure environment (CWE-668). This breaks the fundamental security guarantee of Trusted Execution Environments where secure-world data should be inaccessible from normal-world code.
RemediationAI
Apply processor firmware/microcode updates from the vendor.
