The delayed worker then passes the combined bitmask unmodified to regulator_notifier_call_chain().</p> <p>The core regulator subsystem&#39;s regulator_handle_critical() function evaluates the event parameter using a strict switch statement. If multiple distinct faults occur before the worker runs (e.g., REGULATOR_EVENT_UNDER_VOLTAGE | REGULATOR_EVENT_OVER_CURRENT), the combined bitmask fails to match any case. This leaves the reason as NULL and completely bypasses the critical hw_protection_trigger().</p> <p>Fix the problem by passing events bit by bit to the regulator event handler.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>hwmon: (pmbus) Fix passing events to regulator core</p> <p>Sashiko reports:</p> <p>Commit 754bd2b4a084 (&#34;hwmon: (pmbus/core) Protect regulator operations with mutex&#34;) introduced a worker to batch regulator events over time using atomic_or().
