CVE-2023-53357
high
Description
In the Linux kernel, the following vulnerability has been resolved: md/raid10: check slab-out-of-bounds in md_bitmap_get_counter If we write a large number to md/bitmap_set_bits, md_bitmap_checkpage() will return -EINVAL because 'page >= bitmap->pages', but the return value was not checked immediately in md_bitmap_get_counter() in order to set *blocks value and slab-out-of-bounds occurs. Move check of 'page >= bitmap->pages' to md_bitmap_get_counter() and return directly if true.
