CVE-2025-22847

Local service interruption via out-of-bounds read

Published Mar 4, 2025 · Updated Mar 4, 2025

Out-of-bounds read in OpenHarmony 4.1.0 through 5.0.2 allows local users to interrupt the ArkCompiler eTS Runtime service. OpenHarmony identifies the affected component but has not disclosed the specific function, malformed input, or bounds-checking operation that permits the read. Low-privilege local access and no user interaction are required; successful exploitation causes an availability-only service interruption.
