CVE-2021-47067 (GCVE-0-2021-47067)

Vulnerability from cvelistv5 – Published: 2024-02-29 22:37 – Updated: 2025-05-04 07:03
VLAI?
Summary
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.
Severity ?
No CVSS data available.
