CVSS: 6.5EPSS: 0%CPEs: 288EXPL: 0CVE-2022-29901 – Arbitrary Memory Disclosure through CPU Side-Channel Attacks (Retbleed)
https://notcve.org/view.php?id=CVE-2022-29901
Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution under certain microarchitecture-dependent conditions. Las generaciones de microprocesadores Intel 6 a 8 están afectadas por una nueva variante de Spectre que es capaz de omitir su mitigación de retpoline en el kernel para filtrar datos arbitrarios. Un atacante con acceso de usuario no privilegiado puede secuestrar las instrucciones de retorno para lograr una ejecución arbitraria de código especulativo bajo determinadas condiciones dependientes de la microarquitectura A flaw was found in hw. Non-transparent sharing of branch predictor targets between contexts in some Intel(R) processors may potentially allow an authorized user to enable information disclosure via local access. • http://www.openwall.com/lists/oss-security/2022/07/12/2 http://www.openwall.com/lists/oss-security/2022/07/12/4 http://www.openwall.com/lists/oss-security/2022/07/12/5 http://www.openwall.com/lists/oss-security/2022/07/13/1 https://comsec.ethz.ch/retbleed https://lists.debian.org/debian-lts-announce/2022/09/msg00011.html https://lists.debian.org/debian-lts-announce/2022/12/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fed • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-668: Exposure of Resource to Wrong Sphere •

Unchecked return value in the firmware for some Intel(R) Processors may allow a privileged user to potentially enable an escalation of privilege via local access. Un valor de retorno no comprobado en el firmware de algunos procesadores Intel(R) puede permitir a un usuario con privilegios habilitar potencialmente una escalada de privilegios mediante acceso local. • https://security.netapp.com/advisory/ntap-20220210-0007 https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00527.html • CWE-1188: Initialization of a Resource with an Insecure Default •

CVSS: 5.5EPSS: 0%CPEs: 736EXPL: 0CVE-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 •

https://notcve.org/view.php?id=CVE-2020-8696
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 •
