CWE-20  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 3.14.1 or higher.

Overview

Affected versions of this package are vulnerable to Improper Input Validation. The ioapic_deliver function in virt/kvm/ioapic.c in the Linux kernel through 3.14.1 does not properly validate the kvm_irq_delivery_to_apic return value, which allows guest OS users to cause a denial of service (host OS crash) via a crafted entry in the redirection table of an I/O APIC. NOTE: the affected code was moved to the ioapic_service function before the vulnerability was announced.
