VMware vSphere, Workstation, and Fusion updates enable Hypervisor-Specific Mitigations for L1 Terminal Fault - VMM vulnerability.
The mitigations in this advisory are categorized as Hypervisor-Specific Mitigations described by VMware Knowledge Base article 55636.
vCenter Server, ESXi, Workstation, and Fusion updates include Hypervisor-Specific Mitigations for L1 Terminal Fault - VMM. This issue may allow a malicious VM running on a given CPU core to effectively read the hypervisor’s or another VM’s privileged information that resides sequentially or concurrently in the same core’s L1 Data cache.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the identifier CVE-2018-3646 to this issue.
CVE-2018-3646 has two currently known attack vectors which will be referred to as "Sequential-Context" and "Concurrent-Context."
Attack Vector Summary
Column 5 of the following table lists the action required to mitigate the vulnerability in each release, if a solution is available.
|VMware Product||Product Version||Running On||Severity||Replace_with/Apply_Patch||Mitigation/Workaround|
*These patches DO NOT mitigate the Concurrent-context attack vector previously described by default. For details on the three-phase vSphere mitigation process please see KB55806 and for the mitigation process for Workstation and Fusion please see KB57138.
**These patches include microcode updates required for mitigation of the Sequential-context attack vector. This microcode may also be obtained from your hardware OEM in the form of a BIOS or firmware update. Details on microcode that has been provided by Intel and packaged by VMware is enumerated in the patch KBs found in the Solution section of this document.
