A memory leak flaw in the Linux kernels 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.
The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory.
