Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.

Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.

Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a speculative buffer overflow and side-channel analysis.

Existing UEFI setting restrictions for DCI (Direct Connect Interface) in 5th and 6th generation Intel Xeon Processor E3 Family, Intel Xeon Scalable processors, and Intel Xeon Processor D Family allows a limited physical presence attacker to potentially access platform secrets via debug interfaces.

Systems with microprocessors utilizing speculative execution may allow unauthorized disclosure of information to an attacker with local user access via a side-channel attack on the directional branch predictor, as demonstrated by a pattern history table (PHT), aka BranchScope.

Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis of the data cache.
