Description:
 In the Linux kernel before 4.7, the amd_gpio_remove function in
 drivers/pinctrl/pinctrl-amd.c calls the pinctrl_unregister function,
 leading to a double free.
Ubuntu-Description:
 It was discovered that a double free existed in the AMD GPIO driver in the
 Linux kernel. A local attacker could use this to cause a denial of service
 (system crash) or possibly execute arbitrary code.
