During the ArchLinux installation, after having installed wpa_supplicant and iw I checked if something was wrong with iw dev:
The result was not the one I was expecting to be!
No worries, just check the wpa_supplicant security advisories here, where you can find how to mitigate it:
- Merge the following commits to wpa_supplicant and rebuild it:
P2P: Validate SSID element length before copying it (CVE-2015-1863)
This patch is available from http://w1.fi/security/2015-1/ - Update to wpa_supplicant v2.5 or newer, once available;
- Disable P2P (control interface command “P2P_SET disabled 1” or “p2p_disabled=1” (in each, if multiple interfaces used) wpa_supplicant configuration file;
- Disable P2P from the build (remove CONFIG_P2P=y).
If you have not fixed the issue yet, but you can try following this post.
Hope to be helpful to you all,
