+Candidate: CVE-2008-7256
+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 of an incomplete fix for CVE-2010-1643.
