Description

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.
