CVE-2023-52457

  3. CVE-2023-52457
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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: serial: 8250: omap: no omita la liberación de recursos si pm_runtime_resume_and_get() falla. Devolver un código de error desde .remove() hace que el núcleo del controlador emita el pequeño y útil mensaje de error: eliminar la devolución de llamada devolvió un valor distinto de cero. Esto será ignorado. y luego retire el dispositivo de todos modos. Entonces, en este caso, todos los recursos que no fueron liberados se filtran. Omitir serial8250_unregister_port() tiene el potencial de mantener suficiente UART disponible para desencadenar un use-after-free. Así que reemplace el retorno de error (y con él el pequeño mensaje de error útil) por un mensaje de error más útil y continúe con la limpieza.
