CVSS: 6.5EPSS: 0%CPEs: 897EXPL: 0CVE-2020-0549 – hw: L1D Cache Eviction Sampling
https://notcve.org/view.php?id=CVE-2020-0549
Cleanup errors in some data cache evictions for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. Unos errores de limpieza en algunos desalojos de caché de datos para algunos procesadores Intel(R), pueden permitir a un usuario autenticado habilitar potencialmente una divulgación de información por medio del acceso local. A microarchitectural timing flaw was found on some Intel processors. A corner case exists where data in-flight during the eviction process can end up in the “fill buffers” and not properly cleared by the MDS mitigations. The fill buffer contents (which were expected to be blank) can be inferred using MDS or TAA style attack methods to allow a local attacker to infer fill buffer values. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00016.html https://kc.mcafee.com/corporate/index?page=content&id=SB10318 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.ubunt • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-404: Improper Resource Shutdown or Release •
CVSS: 5.5EPSS: 0%CPEs: 886EXPL: 0CVE-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 •

Improper conditions check in multiple Intel® Processors may allow an authenticated user to potentially enable partial escalation of privilege, denial of service and/or information disclosure via local access.

https://notcve.org/view.php?id=CVE-2018-12207
Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access. Una invalidación inapropiada de las actualizaciones de la tabla de páginas por parte de un sistema operativo invitado virtual para múltiples procesadores Intel® puede habilitar a un usuario autenticado para permitir potencialmente una denegación de servicio del sistema host por medio de un acceso local. A flaw was found in the way Intel CPUs handle inconsistency between, virtual to physical memory address translations in CPU's local cache and system software's Paging structure entries. A privileged guest user may use this flaw to induce a hardware Machine Check Error on the host processor, resulting in a severe DoS scenario by halting the processor. System software like OS OR Virtual Machine Monitor (VMM) use virtual memory system for storing program instructions and data in memory. Virtual Memory system uses Paging structures like Page Tables and Page Directories to manage system memory. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00042.html https://access.redhat.com/errata/RHSA-2019:3916 https://access.redhat.com/errata/RHSA-2019:3936 https://access.redhat.com/errata/RHSA-2019:3941 https://access.redhat.com/errata/RHSA-2020:0026 https://access.redhat.com/errata/RHSA-2020:0028 https://access.redhat.com/errata/RHSA-2020:0204 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/I5WWPW4BSZDDW7VHU427XTVXV7ROOFFW https:/&#x • CWE-20: Improper Input Validation CWE-226: Sensitive Information in Resource Not Removed Before Reuse •
CVSS: 6.5EPSS: 0%CPEs: 324EXPL: 0CVE-2019-11135 – hw: TSX Transaction Asynchronous Abort (TAA)
https://notcve.org/view.php?id=CVE-2019-11135
TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. Una condición de tipo TSX Asynchronous Abort en algunas CPU que utilizan ejecución especulativa puede habilitar a un usuario autenticado para permitir potencialmente una divulgación de información por medio de un canal lateral con acceso local. A flaw was found in the way Intel CPUs handle speculative execution of instructions when the TSX Asynchronous Abort (TAA) error occurs. A local authenticated attacker with the ability to monitor execution times could infer the TSX memory state by comparing abort execution times. This could allow information disclosure via this observed side-channel for any TSX transaction being executed while an attacker is able to observe abort timing. Intel's Transactional Synchronisation Extensions (TSX) are set of instructions which enable transactional memory support to improve performance of the multi-threaded applications, in the lock-protected critical sections. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00045.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00042.html http://packetstormsecurity.com/files/155375/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/12/10/3 http://www.openwall.com/lists/oss-security/2019/12/10/4 http://www.openwall.com/lists/oss-security/2019/12 • CWE-203: Observable Discrepancy •
