Unauthenticated code execution via modem bounds-check omission
Published Aug 14, 2024 · Updated Aug 14, 2024
Memory corruption in MediaTek Modem NR15, NR16, and NR17 allows remote attackers to execute code through network input without authentication. The modem processes untrusted input without a required bounds check, allowing an out-of-bounds memory operation; MediaTek has not disclosed the exact parser or message type. No privileges or user interaction are required, and successful exploitation can compromise confidentiality, integrity, and availability within the modem's security scope.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
