Bring a large pot of salted water to boil and cook pasta until 2 minutes before al dente.
Meanwhile, chop kale and mince garlic, then heat olive oil in another skillet over medium heat and sauté garlic and pepper flakes for 30 seconds.
Add kale and cook for 2 minutes until wilted, then add drained white beans, tomatoes, and broth, and simmer for 5 minutes.
Drain pasta and stir into the skillet with beans and kale, tossing for 1 minute until combined and pasta finishes cooking.
