CVE-2024-20150Network attack vector

Remote modem crash via untrusted data deserialization

Published Jan 6, 2025 · Updated Jan 6, 2025

Deserialization of untrusted data in MediaTek Modem LR12A, LR13, NR15, NR16, and NR17 allows remote attackers to crash the modem. MediaTek identifies a logic error in modem deserialization but has not disclosed the affected parser, input format, or faulty operation. No privileges or user interaction are required; untrusted remote input can terminate modem operation, with no reported ability to read or alter data.
