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.
