CVEID:CVE-2020-24486
**DESCRIPTION:**Intel Processors are vulnerable to a denial of service, caused by improper input validatio in the firmware. By sending a specially-crafted request, a local authenticated attacker could exploit this vulnerability to cause a denial of service.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/203411 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2020-24511
**DESCRIPTION:**Intel Processors could allow a local authenticated attacker to obtain sensitive information, caused by improper isolation of shared resources. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information.
CVSS Base score: 5.6
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/203398 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:N)

CVEID:CVE-2020-24512
**DESCRIPTION:**Intel Processors could allow a local authenticated attacker to obtain sensitive information, caused by the observable timing discrepancy issue. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information.
CVSS Base score: 2.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/203396 for the current score.
