Description:
 The NFSv4 server in the Linux kernel before 4.11.3 does not properly
 validate the layout type when processing the NFSv4 pNFS GETDEVICEINFO or
 LAYOUTGET operand in a UDP packet from a remote attacker. This type value
 is uninitialized upon encountering certain error conditions. This value is
 used as an array index for dereferencing, which leads to an OOPS and
 eventually a DoS of knfsd and a soft-lockup of the whole system.
