--
Summary:
This event is generated when an attempt is made to exploit a known vulnerability in kernel.

--
Impact:
  Loss of integrity. 

--
Detailed Information:
nfsd in the Linux kernel before 2.6.28.9 does not drop the CAP_MKNOD capability before handling a user request in a thread, which allows local users to create device nodes, as demonstrated on a filesystem that has been exported with the root_squash option.
