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 •

https://notcve.org/view.php?id=CVE-2022-0001
Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. La compartición no transparente de selectores de predicción de rama entre contextos en algunos procesadores Intel(R) puede permitir que un usuario autorizado permita potencialmente una divulgación de información por medio del acceso local A flaw was found in hw. The Branch History Injection (BHI) describes a specific form of intra-mode BTI. This flaw allows an unprivileged attacker to manipulate the branch history before transitioning to supervisor or VMX root mode. This issue is an effort to cause an indirect branch predictor to select a specific predictor entry for an indirect branch, and a disclosure gadget at the predicted target will transiently execute. • http://www.openwall.com/lists/oss-security/2022/03/18/2 https://security.netapp.com/advisory/ntap-20220818-0004 https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00598.html https://www.kb.cert.org/vuls/id/155143 https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2022-0001 https://bugzilla.redhat.com/show_bug.cgi?id=2061712 •
CVSS: 6.5EPSS: 0%CPEs: 504EXPL: 0CVE-2022-0002 – hw: cpu: intel: Intra-Mode BTI
https://notcve.org/view.php?id=CVE-2022-0002
Non-transparent sharing of branch predictor within a context in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. La compartición no transparente de selectores de predicción de rama dentro de un contexto en algunos procesadores Intel(R) puede permitir que un usuario autorizado permita potencialmente una divulgación de información por medio del acceso local A flaw was found in hw. The Intra-mode BTI refers to a variant of Branch Target Injection aka SpectreV2 (BTI) where an indirect branch speculates to an aliased predictor entry for a different indirect branch in the same predictor mode, and a disclosure gadget at the predicted target transiently executes. These predictor entries may contain targets corresponding to the targets of an indirect near jump, indirect near call, and near return instructions, even if these branches were only transiently executed. The managed runtimes provide an attacker with the means to create the aliasing required for intra-mode BTI attacks. • http://www.openwall.com/lists/oss-security/2022/03/18/2 https://security.netapp.com/advisory/ntap-20220818-0004 https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00598.html https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2022-0002 https://bugzilla.redhat.com/show_bug.cgi?id=2061721 •
