Details
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.
Severity
7.1 (High)
