Description OSIDB Bzimport 2026-09-17 19:01:46 UTC 
In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: fix handling channel context with different bands in mt76_switch_vif_chanctx()

When performing channel switches on different radios within a short
timeframe, channel contexts with different bands can be carried for
each struct ieee80211_vif_chanctx_switch.

Rework mt76_switch_vif_chanctx() to properly handle this scenario.
