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 •

Systems with microprocessors utilizing speculative execution and Intel software guard extensions (Intel SGX) may allow unauthorized disclosure of information residing in the L1 data cache from an enclave to an attacker with local user access via a side-channel analysis. Los sistemas con microprocesadores que emplean ejecución especulativa y extensiones Intel software guard (Intel SGX) podría permitir la fuga no autorizada de información que reside en la caché de datos L1 desde un enclave a un atacante con acceso de usuario local mediante un análisis de canal lateral. • http://support.lenovo.com/us/en/solutions/LEN-24163 http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20180815-01-cpu-en http://www.securityfocus.com/bid/105080 http://www.securitytracker.com/id/1041451 https://cert-portal.siemens.com/productcert/pdf/ssa-254686.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-608355.pdf https://foreshadowattack.eu https://lists.debian.org/debian-lts-announce/2018/09/msg00017.html https://psirt.global.sonicwall.com/vuln-detail/ • CWE-203: Observable Discrepancy •
CVSS: 5.9EPSS: 0%CPEs: 1095EXPL: 0CVE-2018-3693 – Kernel: speculative bounds check bypass store
https://notcve.org/view.php?id=CVE-2018-3693
Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a speculative buffer overflow and side-channel analysis. Los sistemas con microprocesadores que emplean la ejecución especulativa y la predicción de ramas podría permitir la divulgación no autorizada de información a un atacante con acceso de usuario local mediante un desbordamiento de búfer especulativo y el análisis de canal lateral. An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions past bounds check. The flaw relies on the presence of a precisely-defined instruction sequence in the privileged code and the fact that memory writes occur to an address which depends on the untrusted value. Such writes cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). • https://access.redhat.com/errata/RHSA-2018:2384 https://access.redhat.com/errata/RHSA-2018:2390 https://access.redhat.com/errata/RHSA-2018:2395 https://access.redhat.com/errata/RHSA-2019:1946 https://access.redhat.com/errata/RHSA-2020:0174 https://cdrdv2.intel.com/v1/dl/getContent/685359 https://help.ecostruxureit.com/display/public/UADCE725/Security+fixes+in+StruxureWare+Data+Center+Expert+v7.6.0 https://security.netapp.com/advisory/ntap-20180823-0001 https://www.oracle.com/s • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
