CVE-2023-54244
Description
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
