New 'Retbleed' Speculative Execution Attack Affects AMD and Intel CPUs

Security researchers have uncovered yet another vulnerability affecting numerous older AMD and Intel microprocessors that could bypass current defenses and result in Spectre-based speculative-execution attacks. Dubbed Retbleed by ETH Zurich researchers Johannes Wikner and Kaveh Razavi, the issue ...

hw: cpu: intel: Intra-Mode BTI

A flaw was found in hw. The Intra-mode BTI refers to a variant of Branch Target Injection aka SpectreV2 BTI 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 transiently...
