Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A locking issue exists in the regulator core within the regulator resolve supply() function. When the late enabling of a supply regulator fails, the system triggers a lockdep warning because regulator put() is called without holding the regulator list mutex. Additionally, there is a lack of appropriate locking to prevent concurrent access to the rdev while the supply pointer is being cleared.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
