CVE-2026-10719

Memory corruption via malformed NVMe FLBAS value

Published Jun 2, 2026 · Updated Jun 2, 2026

An out-of-bounds write in Seagate openSeaChest 25.05.3 allows local users to corrupt memory via a crafted NVMe FLBAS value. When --showSupportedFormats processes a bogus namespace FLBAS byte, faulty bounds handling permits a one-byte write past allocated memory and sets that byte to 1. The path requires high local privileges, a malicious NVMe device, and invocation of the format-reporting option; the reported consequence is limited memory corruption.
