Short explanation
A missing bounds check in the MediaTek modem allows a remote attacker controlling a rogue base station to perform an out‑of‑bounds write on a connected UE, causing denial of service. No user interaction or extra privileges are required. Patch status is unknown and no active exploitation is reported.
The flaw can cause service outages in mobile network infrastructure, potentially affecting many users.
What should be done?
- Monitor vendor security bulletins
- Apply patches when officially released
- Restrict connections to trusted base stations
- Deploy network monitoring to detect rogue base stations
- Follow MediaTek security bulletin updates
