Description
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
Result:
