CVE-2013-1935

Red Hat Enterprise Linux 6 - Denial of Service via KVM PV EOI Feature Race Condition

Title source: llm
STIX 2.1

Description

A certain Red Hat patch to the KVM subsystem in the kernel package before 2.6.32-358.11.1.el6 on Red Hat Enterprise Linux (RHEL) 6 does not properly implement the PV EOI feature, which allows guest OS users to cause a denial of service (host OS crash) by leveraging a time window during which interrupts are disabled but copy_to_user function calls are possible.
