Security Bulletin
Summary
IBM Spectrum Copy Data Management can be affected by vulnerabilities in Linux Kernel. An attacker could exploit these vulnerabilities to escalate privileges, gaining elevated privileges or cause the system to crash, to execute arbitrary management commands on the system and cause a denial of service conditions, as described by the CVEs in the "Vulnerability Details" section
Vulnerability Details
CVEID: CVE-2023-35001
DESCRIPTION: Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a nf_tables nft_byteorder_eval out-of-bounds read/write. By sending a specially crafted request, an aattacker could exploit this vulnerability to escalate privileges.
CVSS Base score: 7.8

CVEID: CVE-2023-3090
DESCRIPTION: Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a heap out-of-bounds write flaw due to missing skb->cb initialization in the ipvlan network driver. By sending a specially crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/259385 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-2023-2002
DESCRIPTION: Linux Kernel could allow a remote authenticated attacker to execute arbitrary commands on the system, caused by improper permission check in the Bluetooth subsystem. By sending a specially crafted request, an attacker could exploit this vulnerability to execute arbitrary management commands on the system.
CVSS Base score: 8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/252958 for the current score.
CVSS Vector: (CVSS:3.0/AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2023-3776
DESCRIPTION: Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a use-after-free flaw in the net/sched: cls_fw component. By sending a specially crafted request using the reference counter, an authenticated attacker could exploit this vulnerability to gain elevated privileges.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/261384 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-2023-3390
DESCRIPTION: Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a use-after-free flaw in the netfilter subsystem in net/netfilter/nf_tables_api.c.. By sending a specially crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges.
CVSS Base score: 7.8

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.
