CVE-2025-25057

Local service interruption via nfs_bind memory leak

Published Apr 7, 2025 · Updated Apr 7, 2025

Memory leak in the third_party_NuttX NFS server in OpenHarmony 4.1.0 through 5.0.2 allows local users to interrupt service. The nfs_bind function fails to release allocated memory on an error path, allowing repeated failures to exhaust memory. Low-privileged local access is required; exploitation affects availability without reported data disclosure or modification.
