CVE-2024-21860

Adjacent code execution via DSoftBus use-after-free

Published Feb 2, 2024 · Updated Nov 8, 2024

Use-after-free in OpenHarmony DSoftBus 3.2.0 through 3.2.4 and 4.0.0 allows physically proximate attackers to execute code in applications. The vendor identifies communication_dsoftbus as the affected repository but has not disclosed the function, freed object, or input sequence that reuses it. Exploitation requires adjacent access and high-complexity conditions, needs no privileges or user interaction, and can cross application security boundaries.
