Security Bulletin
Summary
Vulnerabilties in VMware ESXi affect IBM Cloud Pak System. IBM Cloud Pak System has addressed these vulnerabilities.
Vulnerability Details
CVEID: CVE-2022-26373
DESCRIPTION: VMware ESXi could allow a local authenticated attacker to obtain sensitive information, caused by a return-stack-buffer-underflow in the Intel and AMD processors that it utilizes. An attacker could exploit this vulnerability to exploit various side-channel CPU flaws, obtain sensitive information from physical memory about the hypervisor or other virtual machines that reside on the same ESXi host, 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/233046 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-2022-31681
DESCRIPTION: VMware ESXi is vulnerable to a denial of service, caused by a NULL pointer deference flaw in the VMX process. By sending a specially-crafted request, a local authenticated attacker could exploit this vulnerability to cause a denial of service condition on the host machine.
CVSS Base score: 3.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/237952 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:L)
CVEID: CVE-2022-31696
DESCRIPTION: VMware ESXi could allow a local authenticated attacker to bypass security restrictions, caused by a memory corruption flaw in the handling of a network socket. By sending a specially-crafted request, an attacker could exploit this vulnerability to make escape of the ESXi sandbox.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/241821 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H)
CVEID: CVE-2022-31699
DESCRIPTION: VMware ESXi could allow a local authenticated attacker to obtain sensitive information, caused by a heap-based buffer overflow. 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: 4.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/241827 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:N)
IBM X-Force ID: 231872
DESCRIPTION: VMware ESXi could allow a remote attacker to execute arbitrary code on the system, caused by a memory corruption in the TCP/IP kernel module. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute code in the context of the kernel.
CVSS Base score: 8.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/231872 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)

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.
