CVE-2025-39853

In the Linux kernel, the following vulnerability has been resolved:

i40e: Fix potential invalid access when MAC list is empty

list_first_entry() never returns NULL – if the list is empty, it still
returns a pointer to an invalid object, leading to potential invalid
memory access when dereferenced.

Fix this by using list_first_entry_or_null instead of list_first_entry.
