CVE-2026-23246

   
Software afectado LINUX KERNEL
 
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.
