CVE-2024-50040

In the Linux kernel, the following vulnerability has been resolved: igb: Do not bring the device up after non-fatal error Commit 004d25060c78 ("igb: Fix igb_down hung on surprise removal") changed igb_io_error_detected() to ignore non-fatal pcie errors in order to avoid hung task that can happen when igb_down() is called multiple times. This caused an issue when processing transient non-fatal errors. igb_io_resume(), which is called after igb_io_error_detected(), assumes that device is brought down by igb_io_error_detected() if the interface is up. This resulted in panic with stacktrace below.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: igb: No encender el dispositivo después de un error no fatal el commit 004d25060c78 ("igb: Reparar igb_down colgado en eliminación sorpresa") cambió igb_io_error_detected() para ignorar los errores pcie no fatales con el fin de evitar que la tarea se cuelgue que puede suceder cuando se llama a igb_down() varias veces. Esto causó un problema al procesar errores transitorios no fatales. igb_io_resume(), que se llama después de igb_io_error_detected(), asume que el dispositivo es derribado por igb_io_error_detected() si la interfaz está activa. Esto resultó en un pánico con el seguimiento de pila a continuación.

Para solucionar este problema, igb_io_resume() verifica si la interfaz está ejecutándose y si el dispositivo no está inactivo, esto significa que igb_io_error_detected() no inactivó el dispositivo y no es necesario activarlo.
