As a result, if we dereference\nthe acti_netdevs, the null pointer dereference bugs will happen.\nThis patch adds a check to judge whether allocation failure occurs.\nIf it happens, the delayed work will be rescheduled and try again.", "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.
