CVE-2025-62817Network attack vector

Service interruption via NPU session buffer dereference

Published Mar 3, 2026 · Updated Mar 3, 2026

NULL pointer dereference in the NPU of Samsung Exynos 1280, 1380, 1480, 1580, 2200, 2400, and 2500 allows remote attackers to interrupt service. The __pilot_parsing_ncp() function dereferences session->ncp_hdr_buf without ensuring that the session buffer pointer is non-NULL, terminating NPU processing when that state is reached. No privileges or user interaction are required over the network; the documented consequence is availability loss only, with no reported data exposure or modification.
