HighCVSS 8.8/10Last modified Oct 19, 2026

Description

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.
