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

Security Bulletin


Summary

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

Vulnerability Details

CVEID:   CVE-2024-40998
DESCRIPTION:   Linux Kernel is vulnerable to a denial of service, caused by uninitialized Ratelimit_state->Lock Access in __ext4_fill_super(). By sending a specially crafted request, a local authenticated attacker could exploit this vulnerability to cause a denial of service.
CWE:   CWE-1287: Improper Validation of Specified Type of Input
CVSS Source:   IBM X-Force
CVSS Base score:   5.5
CVSS Vector:   (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)

CVEID:   CVE-2024-0641
DESCRIPTION:   Linux Kernel is vulnerable to a denial of service, caused by a flaw in tipc_crypto_key_revoke in net/tipc/crypto.c in the TIPC subsystem. A local authenticated attacker could exploit this vulnerability to trigger a deadlock and potentially crash the system.
CWE:   CWE-833: Deadlock
CVSS Source:   IBM X-Force
CVSS Base score:   4.7
CVSS Vector:   (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H)

CVEID:   CVE-2024-0340
DESCRIPTION:   Linux Kernel could allow a local authenticated attacker to obtain sensitive information, caused by a flaw in the vhost_new_msg function in drivers/vhost/vhost.c. By reading the /dev/vhost-net device file, an attacker could exploit this vulnerability to obtain kernel memory information, and use this information to launch further attacks against the affected system.
CWE:   CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
CVSS Source:   CVE.org
CVSS Base score:   4.4
CVSS Vector:   (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N)

CVEID:   CVE-2024-40958
DESCRIPTION:   Linux Kernel is vulnerable to a denial of service, caused by a use-after-free in net_namespace.c. A local authenticated attacker could exploit this vulnerability to cause a denial of service.
CWE:   CWE-416: Use After Free
CVSS Source:   IBM X-Force
CVSS Base score:   5.5
CVSS Vector:   (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/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.
