MITRE ATT&CK Framework
Technique: Firmware Corruption
For reference, see the MITRE ATT&CK vulnerability types here:
Buffer Overflows occur when a memory location is filled past its expected boundaries. Computer attackers target systems without proper terminating conditions on buffers, which then write the additional information in other locations in memory, overwriting what is there. This could corrupt the data, making the system behave erratically or crash. The new information could include malicious executable code, which might be executed.
