CVE-2023-53357

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

State: Published
Severity: 7.1 High
Published: Sep 17, 2025
Updated: May 11, 2026
Reserved: Sep 16, 2025

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.
