CVE-2026-98675

Missed dip notifications via off-by-one event scanning

Published Oct 18, 2026 · Updated Oct 18, 2026

An off-by-one error in the ADE9000 IRQ1 handler in Linux 6.18 suppresses Phase C voltage-dip events; attacker control is unspecified. ADE9000_ST1_CROSSING_DEPTH sets an exclusive STATUS1 scan limit of 25, excluding the Phase C dip flag at bit 25. The failure affects systems using the ADE9000 driver for dip notifications; the published description establishes missing reports, not a kernel crash or code execution.
