CVE-2005-4811

Linux Kernel 2.6 - Denial of Service via Hugepage Mmap Error Handling

Title source: llm
STIX 2.1

Description

The hugepage code (hugetlb.c) in Linux kernel 2.6, possibly 2.6.12 and 2.6.13, in certain configurations, allows local users to cause a denial of service (crash) by triggering an mmap error before a prefault, which causes an error in the unmap_hugepage_area function.
