Description
Description
In the Linux kernel, the following vulnerability has been resolved:
net: dsa: mt7530: fix NULL dereference on unbind of MT7531 and MT7621
The core and io supplies are only requested for ID_MT7530: both the
devm_regulator_get() in probe and the regulator_enable() in
mt7530_setup() are guarded by the switch id, but mt7530_remove()
disables them unconditionally. On an MT7621 or an MT7531 both pointers
are still NULL from devm_kzalloc(), so rmmod or a sysfs unbind calls
regulator_disable() on NULL.
