Summary

In the mobile_log_d component of MediaTek's products, a vulnerability exists due to improper resolution of symbolic links. This weakness could allow attackers to escalate privileges locally, requiring system execution privileges for exploitation. Importantly, exploitation does not require user interaction, heightening the risk of unauthorized access. A patch is available to mitigate this issue.
