Descriptions

Information exposure through microarchitectural state after transient execution from some register files for some Intel(R) Atom(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

La exposición de la información a través del estado de la microarquitectura después de la ejecución transitoria de algunos archivos de registro para algunos procesadores Intel(R) Atom(R) puede permitir que un usuario autenticado potencialmente habilite la divulgación de información a través del acceso local.

A vulnerability was found in some Intel Atom Processor's microcode. This issue may allow a malicious actor to achieve a local information disclosure, impacting the data confidentiality of the targeted system.

Multiple vulnerabilities have been discovered in the Xen hypervisor, which could result in privilege escalation, denial of service or information leaks.
