Summary
md/raid10: check slab-out-of-bounds in md_bitmap_get_counter
Details

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

md/raid10: check slab-out-of-bounds in mdbitmapget_counter

If we write a large number to md/bitmapsetbits, mdbitmapcheckpage() will return -EINVAL because 'page >= bitmap->pages', but the return value was not checked immediately in mdbitmapget_counter() in order to set *blocks value and slab-out-of-bounds occurs.

Move check of 'page >= bitmap->pages' to mdbitmapget_counter() and return directly if true.
