CVE-2020-8696 – hw: Vector Register Leakage-Active
https://notcve.org/view.php?id=CVE-2020-8696
Improper removal of sensitive information before storage or transfer in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. Una eliminación inapropiada de información confidencial antes del almacenamiento o transferencia en algunos Intel® Processors, puede habilitar a un usuario autenticado para permitir potencialmente una divulgación de información por medio de un acceso local A flaw was found in the Intel Advanced Vector Extensions (AVX) implementation, where a local authenticated attacker with the ability to execute AVX instructions can gather the AVX register state from previous AVX executions. This vulnerability allows information disclosure of the AVX register state. • https://lists.debian.org/debian-lts-announce/2021/02/msg00007.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MAAGIK5CXKBPGY3R4UR5VO56M7MKLZ43 https://security.netapp.com/advisory/ntap-20201113-0006 https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00381 https://access.redhat.com/security/cve/CVE-2020-8696 https://bugzilla.redhat.com/show_bug.cgi?id=1890355 https://access.redhat.com/articles/5569051 • CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer •
CVE-2020-0551
https://notcve.org/view.php?id=CVE-2020-0551
Load value injection in some Intel(R) Processors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.

CVE-2019-14607
https://notcve.org/view.php?id=CVE-2019-14607
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. La verificación de condiciones inadecuadas en múltiples procesadores Intel® puede permitir a un usuario autenticado habilitar potencialmente la escalada parcial de privilegios, la denegación de servicio y / o la divulgación de información a través del acceso local. • https://security.netapp.com/advisory/ntap-20191217-0002 https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00317.html https://www.synology.com/security/advisory/Synology_SA_19_42 • CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVE-2018-12207 – hw: Machine Check Error on Page Size Change (IFU)
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:/ • CWE-20: Improper Input Validation CWE-226: Sensitive Information in Resource Not Removed Before Reuse •
