Summary

In the Linux kernel, the following vulnerability has been resolved:

i40e: Fix kernel crash during reboot when adapter is in recovery mode

If the driver detects during probe that firmware is in recovery mode then i40e_init_recovery_mode() is called and the rest of probe function is skipped including pci_set_drvdata(). Subsequent i40e_shutdown() called during shutdown/reboot dereferences NULL pointer as pci_get_drvdata() returns NULL.

To fix call pci_set_drvdata() also during entering to recovery mode.

Reproducer: 1) Lets have i40e NIC with firmware in recovery mode 2) Run reboot
