In the Linux kernel, the following vulnerability has been resolved:

kprobes: Fix possible use-after-free issue on kprobe registration

When unloading a module, its state is changing MODULESTATELIVE -> MODULESTATEGOING -> MODULESTATEUNFORMED. Each change will take a time. ismoduletextaddress() and moduletextaddress() works with MODULESTATELIVE and MODULESTATEGOING. If we use ismoduletextaddress() and moduletextaddress() separately, there is a chance that the first one is succeeded but the next one is failed because module->state becomes MODULESTATEUNFORMED between those operations.

In checkkprobeaddresssafe(), if the second moduletextaddress() is failed, that is ignored because it expected a kerneltext address. But it may have failed simply because module->state has been changed to MODULESTATEUNFORMED. In this case, armkprobe() will try to modify non-exist module text address (use-after-free).

To fix this problem, we should not use separated ismoduletextaddress() and moduletextaddress(), but use only moduletextaddress() once and do trymoduleget(module) which is only available with MODULESTATELIVE.
