CVE-2025-62814Network attack vector

Service interruption via NPU firmware NULL dereference

Published Mar 3, 2026 · Updated Mar 3, 2026

NULL pointer dereference in the NPU of Samsung Exynos 1280, 1380, 1480, 2200, and 2400 allows remote attackers to interrupt service. The load_fw_utc_vector() function dereferences ft_handle when it is NULL, stopping the affected NPU operation. CISA assesses the path as network-reachable without authentication or user interaction, and the reported consequence is limited to availability.
