USN-6187-1: Linux kernel (IBM) vulnerabilities

2023-06-22 KENNETH 0

USN-6187-1: Linux kernel (IBM) vulnerabilities William Zhao discovered that the Traffic Control (TC) subsystem in the Linux kernel did not properly handle network packet retransmission in certain situations. A local attacker could use this to cause a denial of service (kernel deadlock). (CVE-2022-4269) It was discovered that the TUN/TAP driver in the Linux kernel did not properly initialize socket data. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-1076) It was discovered that the Real-Time Scheduling Class implementation in the Linux kernel contained a type confusion vulnerability in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-1077) It was discovered that the ASUS HID driver in the Linux kernel did not properly handle device removal, leading to a use-after-free vulnerability. A local attacker with physical access [ more… ]

USN-6186-1: Linux kernel vulnerabilities

2023-06-22 KENNETH 0

USN-6186-1: Linux kernel vulnerabilities Patryk Sondej and Piotr Krysiuk discovered that a race condition existed in the netfilter subsystem of the Linux kernel when processing batch requests, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-32233) Gwangun Jung discovered that the Quick Fair Queueing scheduler implementation in the Linux kernel contained an out-of-bounds write vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-31436) Reima Ishii discovered that the nested KVM implementation for Intel x86 processors in the Linux kernel did not properly validate control registers in certain situations. An attacker in a guest VM could use this to cause a denial of service (guest crash). (CVE-2023-30456) It was discovered that the Broadcom [ more… ]

Amazon EC2 Hpc7g 인스턴스 정식 출시 – AWS Graviton3E 프로세서 고성능 컴퓨팅 워크로드용

2023-06-22 KENNETH 0

Amazon EC2 Hpc7g 인스턴스 정식 출시 – AWS Graviton3E 프로세서 고성능 컴퓨팅 워크로드용 AWS re:Invent 2022 기조 연설에서 Adam Selipsky AWS CEO는 일반적으로 고성능 컴퓨팅(HPC) 워크로드는 컴퓨팅 집약적이거나, 컴퓨팅 및 네트워킹 집약적이거나, 데이터 및 메모리 집약적이라고 설명했습니다. 컴퓨팅 워크로드의 예로는 일기 예보, 전산 유체 역학, 금융 옵션 가격 책정 등이 있습니다. 이러한 워크로드를 지원하는 제품으로는 비슷한 컴퓨팅 최적화 x86 기반 인스턴스보다 최대 65% 우수한 가성비를 제공하는 Amazon EC2 Hpc6a 인스턴스가 있습니다. 다른 HPC 워크로드에서는 풍력 터빈, 콘크리트 건물, 산업 장비와 같은 복잡한 구조물의 성능을 모델링해야 합니다. 데이터와 메모리가 충분하지 않으면 이러한 모델을 비용 효율적인 방식으로 실행하는 데 며칠 또는 몇 주가 걸릴 수 있습니다. Amazon EC2 Hpc6id 인스턴스는 더 높은 코어당 메모리 대역폭, 더 빠른 로컬 솔리드 스테이트 드라이브(SSD) 스토리지, Elastic Fabric Adapter(EFA)를 사용하여 향상된 네트워킹을 통해 데이터 및 메모리 집약적인 HPC 워크로드에 최고의 가성비를 제공하도록 설계되었습니다. Amazon EC2 Hpc7g [ more… ]
