"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: sd_zbc: Reject disks with too many zones\n\nsd_zbc_read_zones() computes the number of zones with 64-bit arithmetic and\nstores the result in the unsigned int nr_zones field of struct\nzoned_disk_info, silently truncating counts that exceed 32 bits. The\ntruncated count is later used to size per-zone resources, while the device\nmay still report more zones than fit.\n\nMoreover, sd_zbc_report_zones() counts the reported zones with a signed int\nzone_idx, which overflows past INT_MAX. Reject devices reporting more than\nINT_MAX zones at scan time; such a device is not realistic for any medium\nthat exists today, and accepting it produces inconsistent zone bookkeeping."
