CVEID:   CVE-2020-12360
DESCRIPTION:   Intel Processors could allow a local authenticated attacker to gain elevated privileges on the system, caused by an out-of-bounds read in the firmware. By sending a specially-crafted request, an attacker could exploit this vulnerability to escalate privileges.
CVSS Base score: 5.6
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/203412 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-2020-24486
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.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:C/C:L/I:N/A:N)

Disclaimer

According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
