Security Bulletin: IBM MQ Appliance is affected by multiple kernel vulnerabilities

Description

## Summary IBM MQ Appliance has resolved multiple kernel vulnerabilities. ## Vulnerability Details **CVEID: **[CVE-2017-18595](<https://vulners.com/cve/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](<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](<https://vulners.com/cve/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](<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](<https://vulners.com/cve/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](<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](<https://vulners.com/cve/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](<https://exchange.xforce.ibmcloud.com/vulnerabilities/172524>) for the current score.
