CVE-2025-27242

Local service interruption via reused security-component identifiers

Published Jun 8, 2025 · Updated Jun 9, 2025

Improper input validation in OpenHarmony 5.0.1 through 5.0.3 allows local users to interrupt service through a reused security-component ID. SecCompManager::CreateScId wraps its counter and formerly returned the next identifier without checking componentMap_ for an existing security component. A low-privileged local user can trigger an identifier collision without user interaction, disrupting availability without reported data disclosure or modification.
