## Technical details

An out-of-bounds (OOB) write and read vulnerability exists in Seagate openSeaChest v25.05.3 within the --showSCSIDefects command. The issue stems from improper validation of the defect response length provided by a SCSI device. An attacker can exploit this by connecting a maliciously crafted SCSI device or a drive with an exceptionally large defect list to a system running the utility. Successful exploitation requires high privileges to execute the diagnostic tool and physical or local access to the hardware interface, potentially leading to memory corruption or local code execution.
