GHSA-VW3G-79H8-V7F8

Vulnerability from github – Published: 2024-03-01 00:30 – Updated: 2024-12-10 21:30

Details

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

5.5 (Medium)
