Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> pinctrl: core: delete incorrect free in pinctrl_enable()<br /> <br /> The "pctldev" struct is allocated in devm_pinctrl_register_and_init().<br /> It&amp;#39;s a devm_ managed pointer that is freed by devm_pinctrl_dev_release(),<br /> so freeing it in pinctrl_enable() will lead to a double free.<br /> <br /> The devm_pinctrl_dev_release() function frees the pindescs and destroys<br /> the mutex as well.
