Description
Уязвимость реализации функции tipc_crypto_key_rcv() протокола для внутрикластерного взаимодействия Transparent Inter-Process Communication (TIPC) ядра операционных систем Linux связана с недостаточной проверкой входных данных при обработке MSG_CRYPTO сообщений. Эксплуатация уязвимости может позволить нарушителю, действующему удаленно, вызвать отказ в обслуживании или повысить свои привилегии
