CPUs which have no # microcode update can be mitigated by disabling TSX in the BIOS if # the BIOS provides a tunable. # # Newer CPUs will have a bit set which indicates that the CPU is not # vulnerable, but the MSR to disable TSX will be available # nevertheless as it is an architected MSR. That means the kernel # provides the ability to disable TSX on the kernel command line, # which is useful as TSX is a truly useful mechanism to accelerate # side channel attacks of all sorts. # # 2) iITLB Multihit (NX) - 'No eXcuses' # # iTLB Multihit is an erratum where some Intel processors may incur # a machine check error, possibly resulting in an unrecoverable CPU # lockup, when an instruction fetch hits multiple entries in the # instruction TLB. This can occur when the page size is changed # along with either the physical address or cache type. A malicious # guest running on a virtualized system can exploit this erratum to # perform a denial of service attack. # # The workaround is that KVM marks huge pages in the extended page # tables as not executable (NX). If the guest attempts to execute in # such a page, the page is broken down into 4k pages which are # marked executable. The workaround comes with a mechanism to # recover these shattered huge pages over time. # # Both issues come with full documentation in the hardware # vulnerabilities section of the Linux kernel user's and administrator's # guide. # # Thanks to all patch authors and reviewers who had the extraordinary # priviledge to be exposed to this nuisance. # # Special thanks to Borislav Petkov for polishing the final TAA patch # set and to Paolo Bonzini for shepherding the KVM iTLB workarounds and # providing also the backports to stable kernels for those!" # # * 'x86-pti-for-linus' of
