This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

soc/tegra: regulators: Fix locking up when voltage-spread is out of range

Fix voltage coupler lockup which happens when voltage-spread is out

of range due to a bug in the code. The max-spread requirement shall be

accounted when CPU regulator doesn't have consumers. This problem is

observed on Tegra30 Ouya game console once system-wide DVFS is enabled

in a device-tree.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
