CVE-2025-39853

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> i40e: Fix potential invalid access when MAC list is empty<br /> <br /> list_first_entry() never returns NULL - if the list is empty, it still<br /> returns a pointer to an invalid object, leading to potential invalid<br /> memory access when dereferenced.<br /> <br /> Fix this by using list_first_entry_or_null instead of list_first_entry.
