Mitre

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

wifi: mac80211: bounds-check link id in ieee80211 ml reconfiguration

link id is taken from the ML Reconfiguration element (control & 0x000f), so it can be 0..15. link removal timeout[] has IEEE80211 MLD MAX NUM LINKS (15) elements, so index 15 is out-of-bounds. Skip subelements with link id >= IEEE80211 MLD MAX NUM LINKS to avoid a stack out-of-bounds write.
