CVE-2012-2133

Use-after-free vulnerability in the Linux kernel before 3.3.6, when huge pages are enabled, allows local users to cause a denial of service (system crash) or possibly gain privileges by interacting with a hugetlbfs filesystem, as demonstrated by a umount operation that triggers improper handling of quota data.
