  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: dsa: mt7530: fix NULL dereference on unbind of MT7531 and MT7621\n\nThe core and io supplies are only requested for ID_MT7530: both the\ndevm_regulator_get() in probe and the regulator_enable() in\nmt7530_setup() are guarded by the switch id, but mt7530_remove()\ndisables them unconditionally. On an MT7621 or an MT7531 both pointers\nare still NULL from devm_kzalloc(), so rmmod or a sysfs unbind calls\nregulator_disable() on NULL.",
