Vulnerability from gsd

Details
In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: improve CSA/ECSA connection refusal As mentioned in the previous commit, we pretty quickly found that some APs have ECSA elements stuck in their probe response, so using that to not attempt to connect while CSA is happening we never connect to such an AP. Improve this situation by checking more carefully and ignoring the ECSA if cfg80211 has previously detected the ECSA element being stuck in the probe response. Additionally, allow connecting to an AP that's switching to a channel it's already using, unless it's using quiet mode. In this case, we may just have to adjust bandwidth later. If it's actually switching channels, it's better not to try to connect in the middle of that.

Mejore esta situaci\u00f3n verificando m\u00e1s cuidadosamente e ignorando ECSA si cfg80211 ha detectado previamente que el elemento ECSA est\u00e1 atascado en la respuesta de la sonda. Adem\u00e1s, permita conectarse a un AP que est\u00e9 cambiando a un canal que ya est\u00e9 usando, a menos que est\u00e9 usando el modo silencioso. En este caso, es posible que tengamos que ajustar el ancho de banda m\u00e1s adelante. Si en realidad est\u00e1 cambiando de canal, es mejor no intentar conectarse en medio de eso."
