Summary
In the Linux kernel, the following vulnerability has been resolved: scsi: target: core: Fix integer overflow in UNMAP bounds check sbc_execute_unmap() checks LBA + range does not exceed the device capacity, but does not guard against LBA + range wrapping around on 64-bit overflow. Add an overflow check matching the pattern already used for WRITE_SAME in the same file.
