Summary
Intel Ethernet controllers as used in IBM QRadar SIEM are vulnerable to a denial of service, IBM QRadar SIEM has addressed the applicable CVEs.
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.
