Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
wifi: mac80211: increase scan_ies_len for S1G<br />
<br />
Currently the S1G capability element is not taken into account<br />
for the scan_ies_len, which leads to a buffer length validation<br />
failure in ieee80211_prep_hw_scan() and subsequent WARN in<br />
__ieee80211_start_scan(). This prevents hw scanning from functioning.<br />
To fix ensure we accommodate for the S1G capability length.
