Summary

Vulnerabilities in the Linux kernel affect IBM Storage Virtualize products and could cause various impacts. CVE-2023-1073 CVE-2023-45871 CVE-2023-6356 CVE-2023-6535 CVE-2023-6536 CVE-2023-1206 CVE-2023-5178.

Vulnerability Details

CVEID:CVE-2023-1073
**DESCRIPTION:**Linux Kernel could allow a physical authenticated attacker to gain elevated privileges on the system, caused by a memory corruption flaw in the human interface device (HID) subsystem. By using a specially crafted USB device , an attacker could exploit this vulnerability to gain elevated privileges or cause a denial of service condition.
CVSS Base score: 6.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/251322 for the current score.
CVSS Vector: (CVSS:3.0/AV:P/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2023-45871
**DESCRIPTION:**Linux Kernel is vulnerable to a buffer overflow, caused by improper bounds checking by the IGB driver in drivers/net/ethernet/intel/igb/igb_main.c. By sending a specially crafted request, a remote attacker from within the local network could overflow a buffer and execute arbitrary code or cause a denial of service.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/268717 for the current score.
CVSS Vector: (CVSS:3.0/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2023-6356
**DESCRIPTION:**Linux Kernel is vulnerable to a denial of service, caused by a NULL pointer dereference flaw in the NVMe driver. By sending specially crafted TCP packages when using NVMe over TCP, a remote authenticated attacker could exploit this vulnerability to cause kernel panic, and results in a denial of service condition.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/283792 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2023-6535
**DESCRIPTION:**Linux Kernel is vulnerable to a denial of service, caused by a NULL pointer dereference flaw in the NVMe driver. By sending specially crafted TCP packages when using NVMe over TCP, a remote authenticated attacker could exploit this vulnerability to cause kernel panic, and results in a denial of service condition.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/283790 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2023-6536
**DESCRIPTION:**Linux Kernel is vulnerable to a denial of service, caused by a NULL pointer dereference flaw in the NVMe driver. By sending specially crafted TCP packages when using NVMe over TCP, a remote authenticated attacker could exploit this vulnerability to cause kernel panic, and results in a denial of service condition.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/283791 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2023-1206
**DESCRIPTION:**Linux Kernel is vulnerable to a denial of service, caused by a flaw in the IPv6 connection lookup table. By sending a specially crafted request, a remote attacker could exploit this vulnerability to cause the CPU usage to increase, and results in a denial of service condition.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/259617 for the current score.
CVSS Vector: (CVSS:3.0/AV:A/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2023-5178
**DESCRIPTION:**Linux Kernel could allow a remote attacker to execute arbitrary code on the system, caused by a use-after-free flaw in the nvmet_tcp_free_crypto function in the NVMe-oF/TCP subsystem. By sending a specially crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 8.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/268699 for the current score.
