CVE-2022-21233 – hw: cpu: Intel: Stale Data Read from legacy xAPIC vulnerability
https://notcve.org/view.php?id=CVE-2022-21233
Improper isolation of shared resources in some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access. Un aislamiento inapropiado de los recursos compartidos en algunos procesadores Intel(R) puede permitir que un usuario privilegiado permita potencialmente la divulgación de información a través del acceso local. A flaw was found in hw. The APIC can operate in xAPIC mode (also known as a legacy mode), in which APIC configuration registers are exposed through a memory-mapped I/O (MMIO) page. This flaw allows an attacker who can execute code on a target CPU to query the APIC configuration page. • https://lists.debian.org/debian-lts-announce/2023/04/msg00000.html https://security.netapp.com/advisory/ntap-20220923-0002 https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00657.html https://access.redhat.com/security/cve/CVE-2022-21233 https://bugzilla.redhat.com/show_bug.cgi?id=2115640 https://access.redhat.com/solutions/6971358 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-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 •
CVE-2021-0114
https://notcve.org/view.php?id=CVE-2021-0114
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 •

CVE-2020-24513 – hw: information disclosure on some Intel Atom processors
https://notcve.org/view.php?id=CVE-2020-24513
Domain-bypass transient execution vulnerability in some Intel Atom(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. Una vulnerabilidad en la ejecución transitoria de omisión de dominios en algunos procesadores Intel Atom® puede permitir a un usuario autenticado permitir potencialmente una divulgación de información por medio de un acceso local A potential domain bypass transient execution vulnerability was discovered on some Intel Atom® processors that uses a microarchitectural incidental channel. Currently this channel can reveal supervisor data in the L1 cache and the contents of recent stores. As a consequence, this issue may allow an authenticated user to potentially enable information disclosure via local access. • https://cert-portal.siemens.com/productcert/pdf/ssa-309571.pdf https://lists.debian.org/debian-lts-announce/2021/07/msg00022.html https://www.debian.org/security/2021/dsa-4934 https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00465.html https://access.redhat.com/security/cve/CVE-2020-24513 https://bugzilla.redhat.com/show_bug.cgi?id=1962666 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
