Description OSIDB Bzimport 2026-10-06 09:22:22 UTC 
In the Linux kernel, the following vulnerability has been resolved:

wifi: mac80211: add HE 6 GHz capability in the scan elems len

The HE 6 GHz Band Capability element is in the probe request for
every band if 6 GHz is supported, so add the size to scan_ies_len.

Otherwise, building probe request elements can fail, triggering the
WARN_ON in __ieee80211_start_scan().
