Описание
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.

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.
A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. This vulnerability occurs in the ieee80211_ml_reconfiguration function when processing a Multi-Link (ML) Reconfiguration element. An attacker can provide a crafted link_id value that is not properly bounds-checked, leading to an out-of-bounds write on the stack. This can result in a denial of service (DoS), potentially making the system unavailable.
