Vulnerability Details
CVEID: CVE-2023-51043
DESCRIPTION: Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a use-after-free due to a race condition between a nonblocking atomic commit and a driver unload in drivers/gpu/drm/drm_atomic.c. By sending a specially crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges.
CVSS Base score: 6.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/280864 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2024-1086
DESCRIPTION: Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by use-after-free flaw in the nft_verdict_init() function in the Netfilter subsystem. 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/281122 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-2024-0646
DESCRIPTION: Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by an out-of-bounds memory write flaw in the Transport Layer Security functionality. A local attacker could exploit this vulnerability to gain elevated privileges or cause the system to crash.
CVSS Base score: 7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/279830 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2023-6932
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 ipv4: igmp component. 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/275569 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-2024-26582
DESCRIPTION: Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a use-after-free flaw in the tls_decrypt_sg() function. By sending a specially crafted request, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system.
CVSS Base score: 8.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/283878 for the current score.

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.
