CVE-2013-1798: Linux Kernel

Medium severity, CVSS 6.2. EPSS: 1.4% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: up to and including 3.8.4; version 3.8.0 only; version 3.8.1 only; version 3.8.2 only; version 3.8.3 only
