In the Linux kernel, the following vulnerability has been resolved:
block: avoid possible overflow for chunk_sectors check in blk_stack_limits()
In blk_stack_limits(), we check that the t->chunk_sectors value is a
multiple of the t->physical_block_size value.
However, by finding the chunk_sectors value in bytes, we may overflow
the unsigned int which holds chunk_sectors, so change the check to be
based on sectors.
