CVE-2025-62815

Service interruption via NPU NULL pointer dereference

Published Mar 3, 2026 · Updated Mar 3, 2026

NULL pointer dereference in the NPU of Samsung Exynos 1380, 1480, 1580, 2400, and 2500 allows local users to interrupt service. The set_cpu_affinity() function dereferences npu_proto_drv.ast.thread_ref without first ensuring that the pointer is non-NULL, causing the denial of service. Low-privileged local access is required, no user interaction is needed, and the documented impact is limited to availability rather than data disclosure or modification.
