Описание
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.
Отчет
This issue did not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 5. Future kernel updates for Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux MRG 2 may address this issue.
