CVE-2020-0548 – hw: Vector Register Data Sampling

https://notcve.org/view.php?id=CVE-2020-0548

Cleanup errors in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. Unos errores de limpieza en algunos procesadores Intel(R), pueden permitir a un usuario autenticado habilitar potencialmente una divulgación de información por medio del acceso local. A flaw was found in Intel processors where a local attacker is able to gain information about registers used for vector calculations by observing register states from other processes running on the system. This results in a race condition where store buffers, which were not cleared, could be read by another process or a CPU sibling. The highest threat from this vulnerability is data confidentiality where an attacker could read arbitrary data as it passes through the processor. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00016.html https://lists.debian.org/debian-lts-announce/2020/06/msg00019.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DT2VKDMQ3I37NBNJ256A2EXR7OJHXXKZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/T5OUM24ZC43G4IDT3JUCIHJTSDXJSK6Y https://security.netapp.com/advisory/ntap-20200210-0004 https://usn.ubuntu.com/4385-1 https://www.debian.org/security/2020/dsa-47 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-404: Improper Resource Shutdown or Release •
