staging: rtl8723bs: Fix potential security hole
commit ac33597c0c0d1d819dccfe001bcd0acef7107e7c upstream.
In routine rtw_hostapd_ioctl(), the user-controlled p->length is assumed
to be at least the size of struct ieee_param size, but this assumption is
never checked. This could result in out-of-bounds read/write on kernel
heap in case a p->length less than the size of struct ieee_param is
specified by the user. If p->length is allowed to be greater than the size
of the struct, then a malicious user could be wasting kernel memory.
Fixes commit 554c0a3abf216 ("0taging: Add rtl8723bs sdio wifi driver").
