In the Linux kernel, the following vulnerability has been resolved: ASoC: soc-pcm: don't use soc_pcm_ret() on .prepare callback commit 1f5664351410 ("ASoC: lower "no backend DAIs enabled for ... Port" log severity") ignores -EINVAL error message on common soc_pcm_ret(). It is used from many functions, ignoring -EINVAL is over-kill. The reason why -EINVAL was ignored was it really should only be used upon invalid parameters coming from userspace and in that case we don't want to log an error since we do not want to give userspace a way to do a denial-of-service attack on the syslog / diskspace. So don't use soc_pcm_ret() on .prepare callback is better idea.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ASoC: soc-pcm: no usar soc_pcm_ret() en la devolución de llamada .prepare commit 1f5664351410 ("ASoC: menor severidad del registro "no backend DAIs enabled for ... Port") ignora el mensaje de error -EINVAL en soc_pcm_ret() común. Se usa desde muchas funciones, ignorar -EINVAL es exagerado. La razón por la que se ignoró -EINVAL fue que realmente solo debería usarse en parámetros no válidos que provengan del espacio de usuario y, en ese caso, no queremos registrar un error ya que no queremos darle al espacio de usuario una forma de realizar un ataque de denegación de servicio en el syslog / espacio de disco. Por lo tanto, no usar soc_pcm_ret() en la devolución de llamada .prepare es una mejor idea.
