Security Bulletin: Multiple Vulnerabilities in Intel Firmware affect Cloud Pak System

Summary

Vulnerabilities in Intel firmware affect Cloud Pak System. Cloud Pak system nodes using Intel driver firmware recommended update.

Vulnerability Details

CVEID:CVE-2021-0197
**DESCRIPTION:**Intel Ethernet controllers are vulnerable to a denial of service, caused by a protection mechanism failure in the firmware. By sending a specially-crafted request, a local authenticated attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 5.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/213146 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:H)

CVEID:CVE-2021-0198
**DESCRIPTION:**Intel Ethernet controllers are vulnerable to a denial of service, caused by improper access control in the firmware. By sending a specially-crafted request, a local authenticated attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 4.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/213149 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:H/UI:N/S:U/C:N/I:L/A:H)

CVEID:CVE-2021-0199
**DESCRIPTION:**Intel Ethernet controllers are vulnerable to a denial of service, caused by improper input validation in the firmware. By sending a specially-crafted request, a local authenticated attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 3.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/213151 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:L)

CVEID:CVE-2021-0200
**DESCRIPTION:**Intel Ethernet controllers could allow a local authenticated attacker to gain elevated privileges on the system, caused by an out-of-bounds write flaw in the firmware. By sending a specially-crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges.
CVSS Base score: 6
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/213152 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H)
