Summary
IBM MQ Appliance has resolved multiple kernel vulnerabilities.
Vulnerability Details
CVEID: CVE-2017-18595
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by a double-free in the allocate_trace_buffer function of kernel/trace/trace.c.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/169655 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2018-19985
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by an out-of-bounds read in the hso_get_config_data function in drivers/net/usb/hso.c. A local attacker could exploit this vulnerability to cause the system to crash.
CVSS Base score: 4.6
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/160204 for the current score.
CVSS Vector: (CVSS:3.0/AV:P/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2018-20169
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by improper size validation by the __usb_get_extra_descriptor function in drivers/usb/core/usb.c in the USB subsystem. By sending a specially-crafted request, a local attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 6.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/154367 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2019-19527
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by a use-after-free condition in drivers/hid/usbhid/hiddev.c. By connecting a specially-crafted USB device, an attacker could exploit this vulnerability to cause a kernel panic.
CVSS Base score: 4.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/172524 for the current score.
