CVE-2020-8695 – hw: Information disclosure issue in Intel SGX via RAPL interface
https://notcve.org/view.php?id=CVE-2020-8695
Observable discrepancy in the RAPL interface for some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access. Una discrepancia observable en la interfaz RAPL para algunos Intel® Processors, puede habilitar a un usuario privilegiado para permitir potencialmente una divulgación de información por medio de un acceso local A vulnerability was found in Intel's implementation of RAPL (Running Average Power Limit). An attacker with a local account could query the power management functionality to intelligently infer SGX enclave computation values by measuring power usage in the RAPL subsystem. • https://lists.debian.org/debian-lts-announce/2021/02/msg00007.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AQ24MFBVH3HJW3PNRQBRY4YXKC7GA57W https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GRFC7UAPKAFFH5WX3AMDUBVHLKYQA2NZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MAAGIK5CXKBPGY3R4UR5VO56M7MKLZ43 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NEM2FZWVE4FNGYNQU3WCBAWT • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •

Insufficient access control in a subsystem for Intel (R) processor graphics in 6th, 7th, 8th and 9th Generation Intel(R) Core(TM) Processor Families; Intel(R) Pentium(R) Processor J, N, Silver and Gold Series; Intel(R) Celeron(R) Processor J, N, G3900 and G4900 Series; Intel(R) Atom(R) Processor A and E3900 Series; Intel(R) Xeon(R) Processor E3-1500 v5 and v6, E-2100 and E-2200 Processor Families; Intel(R) Graphics Driver for Windows before 26.20.100.6813 (DCH) or 26.20.100.6812 and before 21.20.x.5077 (aka15.45.5077), i915 Linux Driver for Intel(R) Processor Graphics before versions 5.4-rc7, 5.3.11, 4.19.84, 4.14.154, 4.9.201, 4.4.201 may allow an authenticated user to potentially enable escalation of privilege via local access. Un control de acceso insuficiente en un subsistema para Intel® processor graphics en 6th, 7th, 8th and 9th Generation Intel® Core(TM) Processor Families; Intel® Pentium® Processor J, N, Silver y Gold Series; Intel® Celeron® Processor J, N, G3900 y G4900 Series; Intel® Atom® Processor A y E3900 Series; Intel® Xeon® Processor E3-1500 v5 y v6, E-2100 y E-2200 Processor Families; Intel® Graphics Driver para versiones de Windows anteriores a 26.20.100.6813 (DCH) o 26.20.100.6812 y versiones anteriores a 21.20.x.5077 (también se conoce como 15.45.5077), i915 Linux Driver para Intel® Processor Graphics versiones anteriores a 5.4-rc7, 5.3. 11, 4.19.84, 4.14.154, 4.9.201, 4.4.201, puede habilitar a un usuario autenticado para permitir potencialmente una escalada de privilegios por medio de un acceso local. A flaw was found in the Intel graphics hardware (GPU), where a local attacker with the ability to issue commands to the GPU could inadvertently lead to memory corruption and possible privilege escalation. The attacker could use the GPU blitter to perform privilege MMIO operations, not limited to the address space required to function correctly. • http://packetstormsecurity.com/files/155375/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html https://access.redhat.com/errata/RHSA-2019:3841 https://access.redhat.com/errata/RHSA-2019:3887 https://access.redhat.com/errata/RHSA-2019:3889 https://access.redhat.com/errata/RHSA-2019:3908 https://access.redhat.com/errata/RHSA-2020:0204 https://seclists.org/bugtraq/2019/Nov/26 https://security.netapp.com/advisory/ntap-20200320-0005 https://support.f5.com/csp/article/K73659122 • CWE-284: Improper Access Control •
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 •
