CVE-2025-38644
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: reject TDLS operations when station is not associated syzbot triggered a WARN in ieee80211_tdls_oper() by sending NL80211_TDLS_ENABLE_LINK immediately after NL80211_CMD_CONNECT, before association completed and without prior TDLS setup. This left internal state like sdata->u.mgd.tdls_peer uninitialized, leading to a WARN_ON() in code paths that assumed it was valid. Reject the operation early if not in station mode or not associated.

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: mac80211: rechazar operaciones TDLS cuando la estación no está asociada. syzbot activó una advertencia en ieee80211_tdls_oper() al enviar NL80211_TDLS_ENABLE_LINK inmediatamente después de NL80211_CMD_CONNECT, antes de que se completara la asociación y sin haber configurado previamente TDLS. Esto dejó un estado interno como sdata->u.mgd.tdls_peer sin inicializar, lo que provocó una advertencia WARN_ON() en las rutas de código que asumían que era válido. Rechace la operación antes de tiempo si no está en modo estación o no está asociada."
