CVE-2011-4622 (GCVE-0-2011-4622)

Vulnerability from cvelistv5 – Published: 2012-01-27 15:00 – Updated: 2024-08-07 00:09
VLAI?
Summary
The create_pit_timer function in arch/x86/kvm/i8254.c in KVM 83, and possibly other versions, does not properly handle when Programmable Interval Timer (PIT) interrupt requests (IRQs) when a virtual interrupt controller (irqchip) is not available, which allows local users to cause a denial of service (NULL pointer dereference) by starting a timer.
Severity ?
