NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-headers package and not the kernel-uek-headers package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

The ioapic_read_indirect function in virt/kvm/ioapic.c in the Linux kernel through 3.8.4 does not properly handle a certain combination of invalid IOAPIC_REG_SELECT and IOAPIC_REG_WINDOW operations, which allows guest OS users to obtain sensitive information from host OS memory or cause a denial of service (host OS OOPS) via a crafted application.
