CWE-1338

A hardware device is missing or has inadequate protection features to prevent overheating.

{"xhtml:p":["Hardware, electrical circuits, and semiconductor silicon have thermal side effects, such that some of the energy consumed by the device gets dissipated as heat and increases the temperature of the device. For example, in semiconductors, higher-operating frequency of silicon results in higher power dissipation and heat. The leakage current in CMOS circuits increases with temperature, and this creates positive feedback that can result in thermal runaway and damage the device permanently.","Any device lacking protections such as thermal sensors, adequate platform cooling, or thermal insulation is susceptible to attacks by malicious software that might deliberately operate the device in modes that result in overheating. This can be used as an effective denial of service (DoS) or permanent denial of service (PDoS) attack.","Depending on the type of hardware device and its expected usage, such thermal overheating can also cause safety hazards and reliability issues. Note that battery failures can also cause device overheating but the mitigations and examples included in this submission cannot reliably protect against a battery failure. ","There can be similar weaknesses with lack of protection from attacks based on overvoltage or overcurrent conditions. However, thermal heat is generated by hardware operation and the device should implement protection from overheating."]}
