Ultrablue, 휴대폰용 원격 증명 서버 Ultrablue블루투스를 통한 사용자 친화적인 경량 TPM 원격 증명는 개별 사용자가 자신의 휴대폰으로 부팅 상태 증명을 수행할 수 있게 해주는 솔루션입니다. 이 솔루션은 컴퓨터에서 실행되는 서버증명자 역할와 신뢰할 수 있는 휴대폰에서 실행되는 그래픽 클라이언트 애플리케이션검증자 역할으로 구성됩니다. 일반적인 사용 사례는 컴퓨터 잠금을 해제하기 전에 부트 체인의 무결성을 검증하여 무인 상태의 노트북에 대한 오프라인 공격을 방지하는 것입니다. 또한 펌웨어 업그레이드 후 보안 부팅 문...

CVE-2026-89583

A flaw was found in the Linux kernel's Bluetooth subsystem. An out-of-bounds OOB read vulnerability exists in the eirgetservicedata function due to incorrect length calculation when parsing Extended Inquiry Response EIR advertising data. A remote attacker, by sending a specially crafted periodic...

CVE-2026-89569

A flaw was found in the Linux kernel's Bluetooth RFCOMM subsystem. This vulnerability arises because the system does not properly manage memory when handling Bluetooth security confirmations. A race condition allows a part of the system to free memory that is still in use by another part, leading...
