Descriptions

Incomplete cleanup in specific special register read operations for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

Una limpieza incompleta en operaciones específicas de lectura de registros especiales para algunos procesadores Intel(R) puede permitir que un usuario autenticado permita potencialmente la divulgación de información por medio de acceso local

It was discovered that some Intel processors did not implement sufficient control flow management. A local attacker could use this to cause a denial of service. Joseph Nuzman discovered that some Intel processors did not properly initialise shared resources. A local attacker could use this to obtain sensitive information. Mark Ermolov, Dmitry Sklyarov and Maxim Goryachy discovered that some Intel processors did not prevent test and debug logic from being activated at runtime. A local attacker could use this to escalate privileges.
