In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: enforce HE/EHT cap/oper consistency Xiang Mei reports that mac80211 could crash if eht_cap is set but eht_oper isn't. Rather than fixing that for the individual user(s), enforce that both HE/EHT have consistent elements.
