DESCRIPTION
* CVE-2012-2390: Memory leak in hugetlbfs mmap() failure.
Incorrect error handling in the mmap() implementation for hugetlbfs
could result in reservations not being freed resulting in a denial of
service.
* CVE-2012-2136: Privilege escalation in TUN/TAP virtual device.
The length of packet fragments to be sent wasn't validated before use,
leading to heap overflow. A user having access to TUN/TAP virtual
device could use this flaw to crash the system or to potentially
escalate their privileges.
