Kernel: KVM: export MSR_IA32_TSX_CTRL to guest - incomplete fix for TAA (CVE-2019-11135)

A flaw was found in the fix for CVE-2019-11135, the way Intel CPUs handle speculative execution of instructions when a TSX Asynchronous Abort TAA error occurs. When a guest is running on a host CPU affected by the TAA flaw TAANO=0, but is not affected by the MDS issue MDSNO=1, the guest was to...

hw: TSX Transaction Asynchronous Abort (TAA)

A flaw was found in the way Intel CPUs handle speculative execution of instructions when the TSX Asynchronous Abort TAA error occurs. A local authenticated attacker with the ability to monitor execution times could infer the TSX memory state by comparing abort execution times. This could allow...
