CVSS: 5.6EPSS: 0%CPEs: 463EXPL: 0CVE-2018-3620 – Kernel: hw: cpu: L1 terminal fault (L1TF)
https://notcve.org/view.php?id=CVE-2018-3620
Systems with microprocessors utilizing speculative execution and address translations may allow unauthorized disclosure of information residing in the L1 data cache to an attacker with local user access via a terminal page fault and a side-channel analysis. Los sistemas con microprocesadores que emplean la ejecución especulativa y traducciones de direcciones podría permitir la divulgación no autorizada de información que reside en la caché de datos L1 a un atacante con acceso de usuario local mediante un error de página del terminal y un análisis de canal lateral. Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks. • http://support.lenovo.com/us/en/solutions/LEN-24163 http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20180815-01-cpu-en http://www.securityfocus.com/bid/105080 http://www.securitytracker.com/id/1041451 http://www.vmware.com/security/advisories/VMSA-2018-0021.html http://xenbits.xen.org/xsa/advisory-273.html https://access.redhat.com/errata/RHSA-2018:2384 https://access.redhat.com/errata/RHSA-2018:2387 https://access.redhat.com/errata/RHSA-2018:2388 https: • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •
