Security Bulletin: Multiple Linux Kernel vulnerabilities may affect IBM Elastic Storage System

Security Bulletin


Summary

There are some vulnerabilities in the Linux kernel, used by IBM Elastic Storage System, which could allow a denial of service. Fixes for these vulnerabilities are available.

Vulnerability Details

CVEID:   CVE-2023-32233
DESCRIPTION:   Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a use-after-free flaw in Netfilter nf_tables when processing batch requests. By sending a specially crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges as root.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/254654 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID:   CVE-2023-2124
DESCRIPTION:   Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by an out-of-bounds access flaw in the XFS subsystem due to a missing metadata validation when mounting a user-supplied XFS disk image. By sending a specially crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges or cause a denial of service condition.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/253226 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID:   CVE-2023-1637
DESCRIPTION:   Linux Kernel could allow a local authenticated attacker to obtain sensitive information, caused by a flaw in the X86 CPU Power management options function. By sending a specially crafted request, an attacker could exploit this vulnerability to obtain sensitive information in the memory of the CPU, 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/251406 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)

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.
