## Description

Out of bounds write and reads in openSeaChest’s --showSCSIDefects in Seagate’s openSeaChest v25.05.3 on all supported platforms allows for writing defect information out of bounds for very large defects lists via a very bad drive with lots of defects or a maliciously crafted SCSI device’s defect response length.

## What to do
