Executive Summary

This vulnerability exists in the Linux kernel's mfd: arizona driver, specifically in the wm5102_clear_write_sequencer() function.

If wm5102_clear_write_sequencer() encounters an error, it returns immediately without completing the necessary cleanup sequence.

As a result, regulators remain enabled, causing a resource leak.

The fix changes the function to jump to an error handling label (err_reset) to properly free the resources instead of returning directly.

Impact Analysis

This vulnerability can lead to a resource leak in the system due to regulators remaining enabled when an error occurs.

Resource leaks can cause increased power consumption or instability in hardware components managed by the wm5102 regulator.

Over time, this may degrade system performance or cause unexpected behavior in devices relying on these regulators.
