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.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For linux's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
