Summary

Multiple vulnerabilities in Intel Processors affect Cloud Pak System. IBM Cloud Pak System has addressed vulnerabilities.

Vulnerability Details

CVEID:CVE-2022-21123
**DESCRIPTION:**Intel Processors could allow a local authenticated attacker to obtain sensitive information, caused by incomplete cleanup of multi-core shared buffers. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base score: 6.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/228702 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N)

CVEID:CVE-2022-21125
**DESCRIPTION:**Intel Processors could allow a local authenticated attacker to obtain sensitive information, caused by incomplete cleanup of microarchitectural fill buffers. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.6
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/228703 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-2022-21127
**DESCRIPTION:**Intel Processors could allow a local authenticated attacker to obtain sensitive information, caused by incomplete cleanup in specific special register read operations in the Memory Mapped I/O (MMIO) component. By conducting a specially-crafted read operation, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/228695 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)

CVEID:CVE-2022-21166
**DESCRIPTION:**Intel Processors could allow a local authenticated attacker to obtain sensitive information, caused by incomplete cleanup in specific special register write operations in the Memory Mapped I/O (MMIO) component. By conducting a specially-crafted write operation, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/228696 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)

CVEID:CVE-2022-0001
**DESCRIPTION:**Multiple Intel Processors could allow a local authenticated attacker to obtain sensitive information, caused by an issue with non-transparent sharing of branch predictor selectors between contexts. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base score: 4.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/221228 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N)

CVEID:CVE-2022-0002
**DESCRIPTION:**Multiple Intel Processors could allow a local authenticated attacker to obtain sensitive information, caused by an issue with non-transparent sharing of branch predictor selectors between contexts. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base score: 4.7
