UnknownEPSS 0.39%

Last modified

CVE-2005-4811 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.39% chance of exploitation in the next 30 days.
