https://notcve.org/view.php?id=CVE-2022-26373
Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. Una compartición no transparente de objetivos de predicción de retorno entre contextos en algunos procesadores Intel(R) puede permitir que un usuario autorizado permita potencialmente la divulgación de información por medio de acceso local. A flaw was found in hw. In certain processors with Intel's Enhanced Indirect Branch Restricted Speculation (eIBRS) capabilities, soon after VM exit or IBPB command event, the linear address following the most recent near CALL instruction prior to a VM exit may be used as the Return Stack Buffer (RSB) prediction. • https://lists.debian.org/debian-lts-announce/2022/09/msg00011.html https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html https://security.netapp.com/advisory/ntap-20221007-0005 https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00706.html https://access.redhat.com/security/cve/CVE-2022-26373 https://bugzilla.redhat.com/show_bug.cgi?id=2115065 https://access.redhat.com/solutions/6971358 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

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 •

https://notcve.org/view.php?id=CVE-2020-0549
Cleanup errors in some data cache evictions for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. Unos errores de limpieza en algunos desalojos de caché de datos para algunos procesadores Intel(R), pueden permitir a un usuario autenticado habilitar potencialmente una divulgación de información por medio del acceso local. A microarchitectural timing flaw was found on some Intel processors. A corner case exists where data in-flight during the eviction process can end up in the “fill buffers” and not properly cleared by the MDS mitigations. The fill buffer contents (which were expected to be blank) can be inferred using MDS or TAA style attack methods to allow a local attacker to infer fill buffer values. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00016.html https://kc.mcafee.com/corporate/index?page=content&id=SB10318 https://lists.debian.org/debian-lts-announce/2020/06/msg00019.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DT2VKDMQ3I37NBNJ256A2EXR7OJHXXKZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/T5OUM24ZC43G4IDT3JUCIHJTSDXJSK6Y https://security.netapp.com/advisory/ntap-20200210-0004 https://usn.ubunt • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-404: Improper Resource Shutdown or Release •

https://notcve.org/view.php?id=CVE-2020-0548
Cleanup errors in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. Unos errores de limpieza en algunos procesadores Intel(R), pueden permitir a un usuario autenticado habilitar potencialmente una divulgación de información por medio del acceso local. A flaw was found in Intel processors where a local attacker is able to gain information about registers used for vector calculations by observing register states from other processes running on the system. This results in a race condition where store buffers, which were not cleared, could be read by another process or a CPU sibling. The highest threat from this vulnerability is data confidentiality where an attacker could read arbitrary data as it passes through the processor. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00016.html https://lists.debian.org/debian-lts-announce/2020/06/msg00019.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DT2VKDMQ3I37NBNJ256A2EXR7OJHXXKZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/T5OUM24ZC43G4IDT3JUCIHJTSDXJSK6Y https://security.netapp.com/advisory/ntap-20200210-0004 https://usn.ubuntu.com/4385-1 https://www.debian.org/security/2020/dsa-47 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-404: Improper Resource Shutdown or Release •
