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

Description A flaw exists in the Linux kernel related to ACPI Embedded Controller (EC) query handlers. Specifically, removing custom query handlers could lead to a kernel oops if the module containing the callback function was already unloaded, due to the handler potentially still being used within the EC query workqueue. The issue is addressed by flushing the EC query workqueue during the removal of custom query handlers.
