CVE-2008-7256 Information

Description

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.
