CVE-2019-3887 (GCVE-0-2019-3887)

Vulnerability from cvelistv5 – Published: 2019-04-09 00:00 – Updated: 2024-08-04 19:19

Summary

A flaw was found in the way KVM hypervisor handled x2APIC Machine Specific Rregister (MSR) access with nested(=1) virtualization enabled. In that, L1 guest could access L0's APIC register values via L2 guest, when 'virtualize x2APIC mode' is enabled. A guest could use this flaw to potentially crash the host kernel resulting in DoS issue. Kernel versions from 4.16 and newer are vulnerable to this issue.

Severity

6.7 (Medium)
