dm_table_create in drivers/md/dm-table.c in the Linux kernel through 6.7.4 can attempt to (in alloc_targets) allocate more than INT_MAX bytes, and crash, because of a missing check for struct dm_ioctl.target_count.
The product does not check or incorrectly checks for unusual or exceptional conditions that are not expected to occur frequently during day to day operation of the product.
The product allocates memory based on an untrusted, large size value, but it does not ensure that the size is within expected limits, allowing arbitrary amounts of memory to be allocated.
