In the Linux kernel, the following vulnerability has been resolved:

pinctrl: pinconf-generic: Fully validate 'pinmux' property

The pinconf generic parse dt pinmux() assumes that the 'pinmux' property is not empty when present. This might be not true. With that, the allocator will give a special value in return and not NULL which lead to the crash when trying to access that (invalid) memory. Fix that by fully validating 'pinmux' value, including its length.
