CVE-2024-55045Network attack vector

MAVOBC task stack overflow via undersized stack

Published May 13, 2026 · Updated May 13, 2026

Stack overflow in Firmament-Autopilot FMT-Firmware commit de5aec allows remote attackers to overflow the MAVOBC task stack. The task descriptor in src/task/comm/task_comm.c reserves 4,096 bytes, but the measured task_mavobc_entry call chain consumes 4,400 bytes. The mismatch is documented for the default AMOV ICF5 build; the report identifies no runtime trigger, code execution, or concrete service interruption.
