Description

In the Linux kernel, the following vulnerability has been resolved: PCI/pwrctrl: Fix double cleanup on devm_add_action_or_reset() failure When devm_add_action_or_reset() fails, it calls the passed cleanup function. Hence the caller must not repeat that cleanup. Replace the "goto err_regulator_free" by the actual freeing, as there will never be a need again for a second user of this label.

Executive Summary

This vulnerability in the Linux kernel involves a double cleanup issue in the PCI power control code. Specifically, when the function devm_add_action_or_reset() fails, it calls a cleanup function, so the caller must not call that cleanup again. The vulnerability was due to a redundant cleanup call (a 'double cleanup') which could cause problems. The fix replaced a goto statement with direct freeing code to prevent this double cleanup.

Impact Analysis

The vulnerability could lead to improper resource management in the Linux kernel's PCI power control subsystem, potentially causing system instability or crashes due to double cleanup of resources. This could affect system reliability or availability.
