  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\npinctrl: pinconf-generic: Fully validate 'pinmux' property\n\nThe pinconf_generic_parse_dt_pinmux() assumes that the 'pinmux' property\nis not empty when present. This might be not true. With that, the allocator\nwill give a special value in return and not NULL which lead to the crash\nwhen trying to access that (invalid) memory. Fix that by fully validating\n'pinmux' value, including its length.",
