crypto/algif_skcipher.c in the Linux kernel before 4.4.2 does not verify
that a setkey operation has been performed on an AF_ALG socket before an
accept system call is processed, which allows local users to cause a denial
of service (NULL pointer dereference and system crash) via a crafted
application that does not supply a key, related to the lrw_crypt function
in crypto/lrw.c.
