Network Vulnerability in LAN78XX USB Driver by Linux Kernel

CVE-2025-38385

What is CVE-2025-38385?

A vulnerability in the LAN78XX USB driver within the Linux kernel can lead to a warning during the device disconnect process. This warning occurs due to the redundant call of netif_napi_del() while NAPI is still enabled, which is unnecessary as the unregister_netdev() function manages the NAPI teardown safely. This issue raises alerts without any functional impact on the device, but rectifying it prevents undesired warnings that may obscure other critical notifications in the system logs.
