CVE-2020-24512

Una discrepancia de sincronización observable en algunos Intel® Processors puede permitir a un usuario autenticado permitir potencialmente una divulgación de información por medio de un acceso local

It was discovered that some Intel processors may not properly invalidate cache entries used by Intel Virtualization Technology for Directed I/O. This may allow a local user to perform a privilege escalation attack. Joseph Nuzman discovered that some Intel processors may not properly apply EIBRS mitigations and hence may allow unauthorized memory reads via sidechannel attacks. A local attacker could use this to expose sensitive information, including kernel memory. Various other issues were also addressed.
