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.

A flaw was found in the Linux kernel. The `pinctrl: pinconf-generic` subsystem does not properly validate the 'pinmux' property. An attacker could provide an empty 'pinmux' property, which would cause the system to crash due to invalid memory access. This could lead to a denial of service.
