CVE-2026-10717

Memory corruption via unchecked SCSI defect count

Published Jun 2, 2026 · Updated Jun 2, 2026

Out-of-bounds access in Seagate openSeaChest 25.05.3 and earlier and 26.03.0 through 26.03.1 allows local users to corrupt memory. The --showSCSIDefects path accepts an extreme device-reported defect count without a sufficient upper-bound check, then reads and writes beyond the allocated defect-list buffer. Exploitation requires elevated execution against a defective or malicious SCSI device; 26.03.1 remains affected only on 32-bit builds.
