Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: sparx5: switchdev: se corrige la posible desreferencia de puntero NULL. Como es posible que la asignación falle, devm_kzalloc() puede devolver un puntero NULL. Por lo tanto, es mejor comprobar la 'db' para evitar la desreferencia de puntero NULL.
