Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: ACPI: EC: Fix oops when removing custom query handlers When removing custom query handlers, the handler might still be used inside the EC query workqueue, causing a kernel oops if the module holding the callback function was already unloaded. Fix this by flushing the EC query workqueue when removing custom query handlers. Tested on a Acer Travelmate 4002WLMi
