There is possible NULL pointer dereference if kstr[n]dup failed.

The latest Linux Kernel (2.6.25.3) is affected so previous kernels could be as
well.

Reproducible: Always

------- Comment #1 From Gordon Malm 2008-05-15 17:50:17 0000 ------- 
Only the part of the patch addressing nfs_server.export_path lead to a possible
NULL ptr (the rest is just secure programming practice).
See: http://www.gossamer-threads.com/lists/linux/kernel/906343

That being the case, looks like only 2.6.25 is affected.  2.6.24 and prior use
strncpy carefully to assign mntpath (nfs_server.export_path in 2.6.25) in
nfs4_validate_mount_data.

Need a real programmer to check my statements for accuracy to be sure.
