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

Description A flaw exists in the Linux kernel's PCI/pwrctrl subsystem related to double cleanup operations during failure of the devm add action or reset() function. Specifically, the code incorrectly repeats a cleanup process when this function fails, potentially leading to system instability. The issue occurs because the caller unnecessarily repeats a cleanup function call after devm add action or reset() has already performed it. This can happen when attempting to free resources associated with a power control label.

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