CVE-2014-8173 (GCVE-0-2014-8173)

Vulnerability from cvelistv5 – Published: 2015-03-16 10:00 – Updated: 2024-08-06 13:10
VLAI
Summary
The pmd_none_or_trans_huge_or_clear_bad 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 MADV_WILLNEED madvise system call that leverages the absence of a page-table lock.
