Unity Linux 20.1070a Security Update: kernel (UTSA-2025-384561)

high Nessus Plugin ID 267263

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-384561 advisory.

 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.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
