CVE-2026-73790

System shutdown via memory corruption

Published Oct 14, 2026 · Updated Oct 14, 2026

Memory corruption in HPE NonStop iTP WebServer allows attackers to cause system shutdown via unspecified vectors. The supplied source record identifies memory corruption but provides no faulty operation or affected function, and the linked HPE bulletin was not readable during research. Required privileges, triggering input, and configuration prerequisites remain unverified; the reported consequence is shutdown, not established code execution.
