|Bugzilla:||824345: CVE-2012-2390 kernel: huge pages: memory leak on mmap failure|
The MITRE CVE dictionary describes this issue as:
Memory leak in mm/hugetlb.c in the Linux kernel before 3.4.2 allows local users to cause a denial of service (memory consumption or system crash) via invalid MAP_HUGETLB mmap operations.
This issue did not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 5 as they did not include the upstream commit 84afd99b that introduced this issue. Future kernel updates for Red Hat Enterprise Linux 6 may address this issue.
This has been addressed in Red Hat Enterprise Linux Red Hat Enterprise MRG 2 via https://rhn.redhat.com/errata/RHSA-2012-1150.html
