Name of the Vulnerable Software and Affected Versions
Linux kernel versions through 4.13.5
Description
The issue arises when nested virtualisation is used, and the Linux kernel does not properly traverse guest pagetable entries to resolve a guest virtual address. This allows L1 guest OS users to execute arbitrary code on the host OS or cause a denial of service, resulting in an incorrect index during page walking and potentially crashing the host OS.
Recommendations
For Linux kernel versions through 4.13.5, update to a version later than 4.13.5 to resolve the issue.
At the moment, there is no information about additional mitigation measures for this specific vulnerability.
