CVE-2010-4169

Published: 22 November 2010

Use-after-free vulnerability in mm/mprotect.c in the Linux kernel before 2.6.37-rc2 allows local users to cause a denial of service via vectors involving an mprotect system call.

From the Ubuntu security team

Dave Jones discovered that the mprotect system call did not correctly handle merged VMAs. A local attacker could exploit this to crash the system, leading to a denial of service.
