## Description

In the Linux kernel, the following vulnerability has been resolved:  s390/qeth: validate user buffer length in SNMP and ARP query ioctls  qeth_snmp_command() and qeth_l3_arp_query() allocate a buffer sized by a user-supplied length (udata_len) without checking a lower bound, then set udata_offset to a fixed non-zero value and pass both to a reply callback. The callback bounds-checks the copy with          if ((udata_len - udata_offset) < len)  Both fields are u32, so a udata_len smaller than udata_offset makes the subtraction wrap and the check pass, and the following memcpy() writes past the allocation. A udata_len of 0 also yields ZERO_SIZE_PTR from kzalloc(), which the existing NULL check does not catch.  Reject buffers smaller than udata_offset before allocating, so the callback subtraction can no longer underflow.
