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

Hi Dan,

Do you think any of these could be potential issues:

driver/staging/

rtl8192e/rtllib_rx.c:2442
wlan-ng/cfg80211.c:316
rtl8723bs/os_dep/ioctl_cfg80211.c:1591
rtl8723bs/os_dep/ioctl_cfg80211.c:2738

and if so, findable via Smatch?

Regards,
Lee
