CVE-2017-18174
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.33%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
