CVE-2010-3086

Published: 14 January 2011

include/asm-x86/futex.h in the Linux kernel before 2.6.25 does not properly implement exception fixup, which allows local users to cause a denial of service (panic) via an invalid application that triggers a page fault.

From the Ubuntu Security Team

Tavis Ormandy discovered that the Linux kernel did not properly implement exception fixup. A local attacker could exploit this to crash the kernel, leading to a denial of service.
