Hi. HCL.
I am wondering if there is a mitigation package for (CVE-2019-11135) get released with the November MS patches monthly patches. Thank you.
To enable mitigations for Intel® Transactional Synchronization Extensions (Intel® TSX) Transaction Asynchronous Abort vulnerability (CVE-2019-11135) and Microarchitectural Data Sampling ( CVE-2018-11091 , CVE-2018-12126 , CVE-2018-12127 , CVE-2018-12130 ) along with Spectre [ CVE-2017-5753 & CVE-2017-5715 ] and Meltdown [ CVE-2017-5754 ] variants, including Speculative Store Bypass Disable (SSBD) [ CVE-2018-3639 ] as well as L1 Terminal Fault (L1TF) [ CVE-2018-3615, CVE-2018-3620, and CVE-2018-3646 ] with Hyper-Threading disabled:
reg add “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management” /v FeatureSettingsOverride /t REG_DWORD /d 8264 /f
reg add “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management” /v FeatureSettingsOverrideMask /t REG_DWORD /d 3 /f
If the Hyper-V feature is installed, add the following registry setting:
reg add “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization” /v MinVmVersionForCpuBasedMitigations /t REG_SZ /d “1.0” /f
If this is a Hyper-V host and the firmware updates have been applied: Fully shut down all Virtual Machines. This enables the firmware-related mitigation to be applied on the host before the VMs are started. Therefore, the VMs are also updated when they’re restarted.
Restart the computer for the changes to take effect.
