CVE-2019-19338

A flaw was found in the fix for CVE-2019-11135, in the Linux upstream kernel versions before 5.5 where, 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 no...

SUSE SLES12 Security Update : xen (SUSE-SU-2020:1632-1)

This update for xen to version 4.11.4 fixes the following issues : CVE-2020-0543: Fixed a side channel attack against special registers which could have resulted in leaking of read values to cores other than the one which called it. This attack is known as Special Register Buffer Data Sampling...

hw: L1D Cache Eviction Sampling

A microarchitectural timing flaw was found on some Intel processors. A corner case exists where data in-flight during the eviction process can end up in the “fill buffers” and not properly cleared by the MDS mitigations. The fill buffer contents which were expected to be blank can be inferred usi...
