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 •
