In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: fix out-of-bounds link array access in mt7996_tx()
When mac80211 leaves the link unspecified, mt7996_tx() substitutes the
primary link id of the station or vif. That value is
IEEE80211_LINK_UNSPECIFIED (0xf) until the first link has been added,
and it is then used unchecked to index vif->link_conf[],
mvif->mt76.link[] and sta->link[], all of which hold
IEEE80211_MLD_MAX_NUM_LINKS (15) entries.
Clamp the primary link id to the default link before using it, and use
the clamped value for the link_sta fallback as well.
