Details
In the Linux kernel, the following vulnerability has been resolved:
serial: 8250: omap: Don't skip resource freeing if pm_runtime_resume_and_get() failed
Returning an error code from .remove() makes the driver core emit the little helpful error message:
remove callback returned a non-zero value. This will be ignored.
and then remove the device anyhow. So all resources that were not freed are leaked in this case. Skipping serial8250_unregister_port() has the potential to keep enough of the UART around to trigger a use-after-free.
So replace the error return (and with it the little helpful error message) by a more useful error message and continue to cleanup.
