Recommendation: Monitor — no exploitation signal at the moment.
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: core: delete incorrect free in pinctrl_enable()
The "pctldev" struct is allocated in devm_pinctrl_register_and_init().
It's a devm_ managed pointer that is freed by devm_pinctrl_dev_release(),
so freeing it in pinctrl_enable() will lead to a double free.
The devm_pinctrl_dev_release() function frees the pindescs and destroys
the mutex as well.
