CVSS: 6.5EPSS: 0%CPEs: 1589EXPL: 0CVE-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:/&#x • CWE-20: Improper Input Validation CWE-226: Sensitive Information in Resource Not Removed Before Reuse •

A race condition in specific microprocessors using Intel (R) DDIO cache allocation and RDMA may allow an authenticated user to potentially enable partial information disclosure via adjacent access. Una condición de carrera en microprocesadores específicos que usan la asignación de la memoria caché DDIO y RDMA de Intel (R), puede permitir a un usuario autenticado habilitar potencialmente la divulgación de información parcial por medio de un acceso adyacente. • https://arxiv.org/abs/1909.04841 https://ieeexplore.ieee.org/document/9152768 https://security.netapp.com/advisory/ntap-20190926-0001 https://support.f5.com/csp/article/K43220413 https://support.f5.com/csp/article/K43220413?utm_source=f5support&%3Butm_medium=RSS https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00290.html • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

Page table walks conducted by the MMU during virtual to physical address translation leave a trace in the last level cache of modern AMD processors. By performing a side-channel attack on the MMU operations, it is possible to leak data and code pointers from JavaScript, breaking ASLR. Los paseos de la tabla de páginas llevados a cabo por la MMU durante la traducción de la dirección virtual a física dejan un rastro en la caché de último nivel de los procesadores AMD modernos. Realizando un ataque de canal lateral en las operaciones de MMU, es posible perder datos y punteros de código de JavaScript, rompiendo la ASLR. • http://www.cs.vu.nl/~herbertb/download/papers/anc_ndss17.pdf http://www.securityfocus.com/bid/96457 https://www.vusec.net/projects/anc • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
