Vulnerability Details

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.

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.

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-2023-4004
DESCRIPTION:   Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a flaw in the nft_pipapo_remove function in the netfilter. By sending a specially crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges or cause the system to crash.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/262209 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-2023-20593
DESCRIPTION:   AMD Ryzen, Gen AMD EPYC Processors could allow a local authenticated attacker to obtain sensitive information, caused by a use-after-free flaw in the vzeroupper instruction. By conducting a cache timing attack using a specially crafted application, an attacker could exploit this vulnerability to obtain sensitive data used by other processes, such as passwords and encryption keys, at a rate of 30KB/sec from each CPU core.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/261343 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N)

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
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/259747 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-2023-35788
DESCRIPTION:   Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by an off-by-one flaw in the fl_set_geneve_opt fucntion. 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

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.
