Title
wifi: mac80211: bounds-check link_id in ieee80211_ml_reconfiguration
Summary
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.

"value": "AV:A - The vulnerability is triggered by processing crafted WiFi beacon frames received over the air. The attacker must be within WiFi range of the victim device (adjacent network).\nAC:L - The attacker can reliably trigger this by broadcasting crafted beacon frames with a spoofed BSSID containing a malicious ML Reconfiguration element. No special conditions beyond WiFi proximity are needed once the victim is associated.\nPR:N - No privileges or authentication are required. WiFi beacon frames are unencrypted management frames that any device in range can inject by spoofing the associated AP\u0027s BSSID.\nUI:N - No user interaction is required. The victim device automatically processes beacon frames from its associated AP while connected to a WiFi network.\nS:U - The vulnerability affects the kernel itself; exploitation stays within the same security authority (kernel context). There is no crossing of a virtualization or sandbox boundary.\nC:H - This is a stack-based out-of-bounds write where the attacker controls the written value. Stack corruption can be leveraged to read arbitrary memory through carefully crafted exploitation techniques.\nI:H - The stack-based buffer overflow allows the attacker to write a controlled 2-byte value past the array bounds on the stack, potentially corrupting return addresses or other stack data, which can lead to arbitrary code execution in kernel context.\nA:H - The stack corruption will at minimum cause a kernel crash/oops, resulting in a denial of service. Stack buffer overflows reliably crash the kernel when they corrupt critical stack data."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
