The vulnerability is triggered by specially-crafted TPM2 command packets that then trigger the issue when the state of the TPM2's volatile state is written. The highest threat from this vulnerability is to system availability. This issue affects libtpms versions before 0.8.5, before 0.7.9 and before 0.6.6."

La vulnerabilidad es desencadenada mediante paquetes de comandos del TPM2 especialmente dise\u00f1ados que luego desencadenan el problema cuando es escrito el estado vol\u00e1til del TPM2. La mayor amenaza de esta vulnerabilidad es la disponibilidad del sistema. Este problema afecta a libtpms versiones anteriores a 0.8.5, 0.7.9 y 0.6.6"
