[PATCH v2] staging: rtl8192e: Fix possible buffer overflow in _rtl92e_wx_set_scan

2021-02-26 Thread Lee Gibson
Function _rtl92e_wx_set_scan calls memcpy without checking the length. A user could control that length and trigger a buffer overflow. Fix by checking the length is within the maximum allowed size. Changes in v2: Changed to use min_t as per useful suggestions Signed-off-by: Lee Gibson
