What to do
AI-suggested
A fix for this vulnerability has been implemented in the Linux kernel by adjusting the initialization sequence and error handling in the sfc driver. Users should apply the official Linux kernel updates that include this fix once available.
Description
CVE-2025-37860 is a medium severity vulnerability in the Linux kernel involving NULL pointer dereferences in the ef100_process_design_param() function of the sfc driver. The issue arises because certain functions run before the network device is created, leading to unsafe calls that can cause kernel crashes. The problem was fixed by moving network interface calls to a safer initialization phase and improving error reporting.
