Doc Text:	A vulnerability was found in the Linux kernel's ethernet lag_conf.c driver in the nfp_fl_lag_do_work() function, where a NULL pointer dereference can occur due to a lack of proper checks. The scenario is caused when the function attempts to call kmalloc_array(), which returns as NULL because the physical memory has run out, and the corresponding value acti_netdevs is then used. This flaw can result in system instability.	Story Points:	---
