Summary

TSSC/IMC is vulnerable to aritrary code excecution due to kernel. A patch has been provided that updates the kernel library. CVE-2022-42896, CVE-2023-1281, CVE-2023-1829, CVE-2023-2124, CVE-2023-2194, CVE-2023-2235.

Vulnerability Details

CVEID:CVE-2022-42896
**DESCRIPTION:**Linux Kernel could allow a remote attacker from within the local network to execute arbitrary code on the system, caused by multiple use-after-free vulnerabilities in the net/bluetooth/l2cap_core.c’s l2cap_connect and l2cap_le_connect_req functions. By using Bluetooth within proximity of the victim, an attacker could exploit this vulnerability to execute arbitrary code on the system and leak kernel memory.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/240820 for the current score.
CVSS Vector: (CVSS:3.0/AV:A/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L)

CVEID:CVE-2023-1281
**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 traffic control index filter (tcindex). By sending a specially crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges to root.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/250930 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-2023-1829
**DESCRIPTION:**Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a use-after-free flaw when deleting a perfect hash filter in the tcindex_delete() function. 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/252501 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

CVEID:CVE-2023-2194
**DESCRIPTION:**Linux Kernel could allow a local authenticated attacker to execute arbitrary code on the system, caused by an out-of-bounds write flaw in the SLIMpro I2C device driver. By sending a specially crafted request, an attacker could exploit this vulnerability to execute arbitrary code or cause the system to crash.
CVSS Base score: 6.7

CVEID:CVE-2023-2235
**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 perf_group_detach function in the Performance Events system. By sending a specially crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges.
