In the Linux kernel, the following vulnerability has been resolved:
drivers/md/md-bitmap: check the return value of md_bitmap_get_counter()
Check the return value of md_bitmap_get_counter() in case it returns NULL pointer, which will result in a null pointer dereference.
v2: update the check to include other dereference
