mwifiex: Fix possible buffer overflows in mwifiex_ret_wmm_get_status()
[ Upstream commit 3a9b153c5591548612c3955c9600a98150c81875 ]
mwifiex_ret_wmm_get_status() calls memcpy() without checking the
destination size.Since the source is given from remote AP which
contains illegal wmm elements , this may trigger a heap buffer
overflow.
Fix it by putting the length check before calling memcpy().
