NVD Description

Note: Versions mentioned in the description apply only to the upstream perf-debuginfo package and not the perf-debuginfo package as distributed by Rocky-Linux. See How to fix? for Rocky-Linux:8 relevant fixed versions and status.

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.
