- Summary
- [none]
- Details
-
The pmdnoneortranshugeorclearbad function in include/asm-generic/pgtable.h in the Linux kernel before 3.13 on NUMA systems does not properly determine whether a Page Middle Directory (PMD) entry is a transparent huge-table entry, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted MADVWILLNEED madvise system call that leverages the absence of a page-table lock.
