Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> platform/x86: asus-wmi: Fix racy registrations<br /> <br /> asus_wmi_register_driver() may be called from multiple drivers<br /> concurrently, which can lead to the racy list operations, eventually<br /> corrupting the memory and hitting Oops on some ASUS machines.<br /> Also, the error handling is missing, and it forgot to unregister ACPI<br /> lps0 dev ops in the error case.<br /> <br /> This patch covers those issues by introducing a simple mutex at<br /> acpi_wmi_register_driver() &amp; *_unregister_driver, and adding the<br /> proper call of asus_s2idle_check_unregister() in the error path.
