Title: kernel de Linux
Description: En el kernel de Linux, se resolvió la siguiente vulnerabilidad: usb: dwc3: core: soluciona el pánico del kernel cuando se reinicia. Cuando se reinicia el sistema, llama a dwc3_shutdown y todos los debugfs para dwc3 se eliminan primero, cuando el dispositivo intenta realizar deinit. y elimina debugfs para sus endpoints, se encuentra con el problema de desreferencia del puntero NULL cuando se llama a debugfs_lookup. Solucionelo eliminando todos los debugfs de dwc3 posteriores a dwc3_drd_exit.
