Descriptions
In the Linux kernel, the following vulnerability has been resolved:
nfp: flower: handle acti_netdevs allocation failure
The kmalloc_array() in nfp_fl_lag_do_work() will return null, if
the physical memory has run out. As a result, if we dereference
the acti_netdevs, the null pointer dereference bugs will happen.
This patch adds a check to judge whether allocation failure occurs.
If it happens, the delayed work will be rescheduled and try again.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nfp: flor: manejar el error de asignación de acti_netdevs El kmalloc_array() en nfp_fl_lag_do_work() devolverá nulo, si la memoria física se ha agotado. Como resultado, si eliminamos la referencia a acti_netdevs, se producirán errores de desreferencia del puntero nulo. Este parche agrega una verificación para juzgar si se produce una falla en la asignación. Si esto sucede, el trabajo retrasado se reprogramará y se intentará nuevamente.
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.
