What to do
AI-suggested
A fix has been implemented in the Linux kernel to check that the dummy regulator has been probed before use. Users should apply the official kernel updates that include this fix.
Description
CVE-2025-22008 is a medium-severity vulnerability in the Linux kernel related to the regulator subsystem. The issue arises from asynchronous driver probing, where the dummy regulator may be accessed before it has been properly probed. This can lead to a denial of service condition due to improper handling of the regulator state.
