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 amultiple of the t->physical_block_size value.However, by finding the chunk_sectors value in bytes, we may overflowthe unsigned int which holds chunk_sectors, so change the check to bebased on sectors.
