In the Linux kernel, the following vulnerability has been resolved: can: dev: can_put_echo_skb(): don't crash kernel if can_priv::echo_skb is accessed out of bounds If the "struct can_priv::echoo_skb" is accessed out of bounds, this would cause a kernel crash. Instead, issue a meaningful warning message and return with an error. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: can: dev: can_put_echo_skb(): no bloquee el kernel si se accede a can_priv::echo_skb fuera de los límites. Si se accede a "struct can_priv::echoo_skb" fuera de los límites, esto provocaría un fallo del kernel.
