{"id":"DEBIAN-CVE-2023-53114","details":"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: [  139.084698] i40e: Intel(R) Ethernet Connection XL710 Network Driver [  139.090959] i40e: Copyright (c) 2013 - 2019 Intel Corporation.
