Remote service interruption via improperly validated modem input
Published Jun 3, 2024 · Updated Aug 1, 2024
Out-of-bounds write in MediaTek modem firmware NR17 and NR17R allows remote attackers to interrupt service through malformed input. The modem improperly validates input before writing beyond an intended buffer, but MediaTek has not disclosed the affected parser or message format. No privileges or user interaction are required; the vendor reports denial of service only and does not claim code execution or data compromise.
