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.
