CVE-2024-36940

pinctrl: core: delete incorrect free in pinctrl_enable()

State: Published
Severity: 7.8 High
Published: May 30, 2024
Updated: Oct 15, 2026

Description

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.
