https://notcve.org/view.php?id=CVE-2019-0152
Insufficient memory protection in System Management Mode (SMM) and Intel(R) TXT for certain Intel(R) Xeon(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access. Una protección insuficiente de la memoria en el modo System Management (SMM) e Intel® TXT para ciertos procesadores Intel® Xeon®, puede habilitar a un usuario privilegiado para permitir potencialmente una escalada de privilegios por medio de un acceso local. • https://cert-portal.siemens.com/productcert/pdf/ssa-398519.pdf https://support.f5.com/csp/article/K34425791?utm_source=f5support&%3Butm_medium=RSS https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbhf03971en_us https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00240.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
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 •
