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.
