NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt_debug-devel package and not the kernel-rt_debug-devel package as distributed by SLES.

A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the memory pages. A local user could use this flaw to get unauthorized access to some data.
