CVE-2008-7256

UnknownEPSS 0.34%

Last modified

CVE-2008-7256 is a vulnerability of currently unknown severity. mm/shmem.c in the Linux kernel before 2.6.28-rc8, when strict overcommit is enabled and CONFIG_SECURITY is disabled, does not properly handle the export of shmemfs objects by knfsd, which allows attackers to cause a denial of service (NULL pointer dereference and knfsd crash) or possibly have unspecified other impact via unknown vectors. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-1643.. EPSS estimates a 0.34% chance of exploitation in the next 30 days.
