Description

Intra-mode BTI refers to a variant of BTI (Branch Target Injection aka SpectreV2) where an indirect branch speculates to an aliased predictor entry for a different indirect branch in the same predictor mode , and a disclosure gadget at the predicted target will transiently execute. Such predictor entries may contain targets corresponding to the targets of indirect near jump, indirect near call and/or near return instructions, even if these branches were only transiently executed. Managed runtimes can provide an attacker with the means to create the aliasing required for intra-mode BTI attacks.
