CVE-2025-20091

Local code execution via DSoftBus use-after-free

Published Mar 4, 2025 · Updated Mar 4, 2025

Use-after-free in OpenHarmony 4.1.0 through 5.0.2 allows local users to execute arbitrary code in pre-installed applications. The flaw is in Communication DSoftBus, but OpenHarmony has not disclosed the affected object or the lifetime operation that leaves it accessible after release. Exploitation requires low local privileges and a restricted scenario; published material does not define that scenario or identify the affected pre-installed application.
