Type:
CWE-476 NULL Pointer Dereference
Publication date:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: wfx: fix possible NULL pointer dereference in wfx_set_mfp_ap()<br /> <br /> Since &amp;#39;ieee80211_beacon_get()&amp;#39; can return NULL, &amp;#39;wfx_set_mfp_ap()&amp;#39;<br /> should check the return value before examining skb data. So convert<br /> the latter to return an appropriate error code and propagate it to<br /> return from &amp;#39;wfx_start_ap()&amp;#39; as well. Compile tested only.
