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.
