CPU Flaw Allows Private Key Reconstruction; Red Hat Issues Advisory
What happened
A vulnerability was identified in Intel CPUs, specifically related to the Hyper-Threading feature, which could leak information between execution threads via the cache state. This flaw allows for the reconstruction of an RSA private key. Jose Santos, President at RSA, was involved in the effort to quietly notify security teams before the issue was publicly disclosed. Red Hat has since issued an advisory regarding the flaw.
