Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: nl80211: fix NL80211_ATTR_MLO_LINK_ID off-by-one Since the netlink attribute range validation provides inclusive checking, the *max* of attribute NL80211_ATTR_MLO_LINK_ID should be IEEE80211_MLD_MAX_NUM_LINKS - 1 otherwise causing an off-by-one.
