medium Nessus Plugin ID 308901

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-2026-011137 advisory.

 In the Linux kernel, the following vulnerability has been resolved:

 regulator: core: fix resource leak in regulator_register()

 I got some resource leak reports while doing fault injection test:

 OF: ERROR: memory leak, expected refcount 1 instead of 100, of_node_get()/of_node_put() unbalanced - destroy cset entry:
 attach overlay node /i2c/pmic@64/regulators/buck1

 After calling regulator_resolve_supply(), the 'rdev->supply' is set by set_supply(), after this set, in the error path, the resources need be released, so call regulator_put() to avoid the leaks.

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.
