Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.3

Description The issue is caused by a buffer overflow in the mp override legacy irq() function, located in arch/x86/kernel/acpi/boot.c. This allows local users to gain privileges via a crafted ACPI table.

Recommendations For Linux kernel versions prior to 3.3, consider updating to a version that contains a fix for this issue as a permanent solution. As a temporary workaround, consider restricting access to the mp override legacy irq() function to minimize the risk of exploitation.
