Description OSIDB Bzimport 2026-06-24 18:04:42 UTC

In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: mt7925: prevent NULL vif dereference in mt7925_mac_write_txwi

Check for a NULL `vif` before accessing `ieee80211_vif_is_mld(vif)` to
avoid a potential kernel panic in scenarios where `vif` might not be
initialized.
