Description OSIDB Bzimport 2026-06-25 10:03:58 UTC 
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.
