Summary

IBM RackSwitch firmware products have addressed the following Kernel vulnerabilities.

Vulnerability Details

CVEID:CVE-2020-13974
**DESCRIPTION:**Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by an integer overflow in the drivers/tty/vt/keyboard.c. By sending a specially crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 8.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/183251 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2020-10732
**DESCRIPTION:**Linux Kernel could allow a local authenticated attacker to obtain sensitive information, caused by a flaw in the implementation of Userspace core dumps. By sending a specially crafted request, an attacker could exploit this vulnerability to obtain sensitive information or cause a program to crash.
CVSS Base score: 3.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/181554 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N)

CVEID:CVE-2020-14314
**DESCRIPTION:**Linux Kernel is vulnerable to a denial of service, caused by a memory out-of-bounds read flaw. By sending a specially crafted request, a local attacker could exploit this vulnerability to cause the system to crash.
CVSS Base score: 4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/188395 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID:CVE-2020-12770
**DESCRIPTION:**Linux Kernel is vulnerable to a denial of service, caused by an issue with sg_write lacks an sg_remove_request call in a certain failure case. By sending a specially-crafted request, a local attacker could exploit this vulnerability to cause a panic.
CVSS Base score: 6.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/181750 for the current score.
