CVE-2022-49618 Information

Description

In the Linux kernel the following vulnerability has been resolved:

pinctrl: aspeed: Fix potential NULL dereference in aspeed_pinmux_set_mux()

pdesc could be null but still dereference pdesc->name and it will lead to a null pointer access. So we move a null check before dereference.
