Root privilege escalation via LiteOS_A buffer overflow
Published Feb 7, 2025 · Updated Feb 12, 2025
A buffer overflow in OpenHarmony LiteOS_A 4.1.0 through 4.1.2 allows local users to gain root privileges and disclose sensitive information. The published record identifies LiteOS_A as the affected component but does not disclose the vulnerable function, input, or unchecked copy operation. Exploitation requires local low-privilege access and no user interaction; a successful overflow crosses a privilege boundary, exposes sensitive data, and can compromise system integrity and availability.
