In the Linux kernel, the following vulnerability has been resolved:
md/raid1: fix memory leak in raid1 run()
raid1 run() calls setup conf() which registers a thread via
md register thread(). If raid1 set limits() fails, the previously
registered thread is not unregistered, resulting in a memory leak
of the md thread structure and the thread resource itself.
Add md unregister thread() to the error path to properly cleanup
the thread, which aligns with the error handling logic of other paths
in this function.
Compile tested only. Issue found using a prototype static analysis tool
and code review.
