Description
A race condition vulnerability was found in the Linux kernel's cros_ec_uart driver. This issue occurs because the cros_ec_uart_probe() function calls devm_serdev_device_open() before initializing the serdev->ops via serdev_device_set_client_ops(). This mismatch can cause a NULL pointer dereference when accessing serdev->ops->receive_buf, leading to a crash.
