CVE-2022-48840

17
FAUCET Score

CVE-2022-48840 is a vulnerability in the Linux kernel's iavf driver that causes a system hang during reboot or shutdown. This occurs due to an infinite loop in the iavf_remove() function when the adapter is already in a removal state, specifically affecting systems utilizing Virtual Functions (VFs) with ice or i40e drivers. Rated as Medium severity (CVSS 5.5), this vulnerability has a local attack vector (AV:L) and low attack complexity (AC:L), requiring local user privileges (PR:L). The primary impact is a denial of service (A:H) as the system becomes unresponsive during shutdown, with no impact on confidentiality or integrity. There is no evidence of active exploitation, nor are there any known public exploit codes available in Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage for this CVE are minimal, indicating a low level of public attention.
