CVE-2011-4622
Last modified
CVE-2011-4622 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.36% chance of exploitation in the next 30 days.
