CVE-2014-2038

The nfs_can_extend_write function in fs/nfs/write.c in the Linux kernel
before 3.13.3 relies on a write delegation to extend a write operation
without a certain up-to-date verification, which allows local users to
obtain sensitive information from kernel memory in opportunistic
circumstances by writing to a file in an NFS filesystem and then reading
the same file.
