Descriptions

In the Linux kernel, the following vulnerability has been resolved:

wifi: cfg80211: check A-MSDU format more carefully

If it looks like there's another subframe in the A-MSDU
but the header isn't fully there, we can end up reading
data out of bounds, only to discard later. Make this a
bit more careful and check if the subframe header can
even be present.

En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: wifi: cfg80211: comprueba más detenidamente el formato A-MSDU Si parece que hay otra subtrama en el A-MSDU pero el encabezado no está completamente ahí, podemos terminar leyendo datos fuera de límites, sólo para descartarlo más tarde. Haga esto un poco más cuidadoso y verifique si el encabezado del subtrama puede estar presente.
