CVE-2026-98425
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad:
wifi: mac80211: no emitir advertencia cuando una IBSS no tiene canal que escanear
ieee80211_request_ibss_scan() emite una advertencia cuando la normativa no deja ningún canal permitido, pero eso puede ocurrir porque el dominio regulatorio puede cambiar mientras la IBSS está en funcionamiento, y puede seguir funcionando brevemente durante el periodo de gracia de 60 s hasta que se apaga.
Simplemente se elimina la advertencia en este caso.
