In the Linux kernel, the following vulnerability has been resolved: net: stmmac: make sure that ptp_rate is not 0 before configuring EST If the ptp_rate recorded earlier in the driver happens to be 0, this bogus value will propagate up to EST configuration, where it will trigger a division by 0. Prevent this division by 0 by adding the corresponding check and error code.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: stmmac: asegúrese de que ptp_rate no sea 0 antes de configurar EST Si el ptp_rate registrado anteriormente en el controlador resulta ser 0, este valor falso se propagará hasta la configuración de EST, donde activará una división por 0. Evite esta división por 0 agregando el código de verificación y error correspondiente.
