Summary
In the Linux kernel, a vulnerability was found in the mfd: arizona driver where the wm5102_clear_write_sequencer() function may return an error, bypassing the cleanup sequence and causing a regulator resource leak. Regulators remain enabled, leading to resource exhaustion.
Risk Assessment
The risk involves depletion of regulator resources, which can lead to system instability, increased power consumption, or hardware failure under prolonged operation.
Recommendation
It is recommended to immediately update the Linux kernel to a version containing the fix, which changes the direct return to a jump to the err_reset label, ensuring proper regulator release.
