Unauthenticated code execution via unchecked buffer write
Published Jan 2, 2024 · Updated Apr 17, 2025
Out-of-bounds write in the MediaTek Modem IMS Stack in LR13 NR15, NR16, and NR17 allows remote attackers to execute code. The stack processes untrusted remote input without the required bounds check and writes beyond the destination buffer. No privileges or user interaction are required, and successful exploitation executes attacker-controlled code in the modem context.
