  "title": "wifi: mt76: mt7996: fix out-of-bounds link array access in mt7996_tx()",
  "description": "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-\u003Elink_conf[], mvif-\u003Emt76.link[] and sta-\u003Elink[], 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.",
