CVE-2025-24298

Local code execution via liteos_a use-after-free

Published Aug 11, 2025 · Updated Aug 11, 2025

Use-after-free in OpenHarmony 5.0.3 through 5.0.3.x allows local users to execute arbitrary code in the trusted computing base. OpenHarmony identifies liteos_a and the trusted computing base as the locus, but has not disclosed the freed object, triggering operation, or faulty lifetime handling. A low-privileged local account is required, and successful exploitation crosses a security boundary to execute code and interrupt service without altering protected data.
