NULL pointer dereference in Linux kernel - CVE-2025-37860

Vulnerability identifier: #VU107700

CSH Severity: Low

CVSS v4 BT: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2025-37860

CWE-ID: CWE-476

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to NULL pointer dereference within the ef100_process_design_param() and ef100_check_design_params() functions in drivers/net/ethernet/sfc/ef100_nic.c, within the ef100_probe_netdev() function in drivers/net/ethernet/sfc/ef100_netdev.c. A local user can perform a denial of service (DoS) attack.
