Security Bulletin
Summary
IBM QRadar Network Security is affected by Linux kernel vulnerabilities
Vulnerability Details
CVEID: CVE-2019-7221
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by a use-after-free in the way KVM hypervisor emulates a preemption timer for L2 guests when nested (=1) virtualization is enabled.. A local authenticated attacker could exploit this vulnerability to crash the host kernel and possibly gain privileged access to a system.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/157079 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H)
CVEID: CVE-2019-6974
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by the improper handling of reference counting by kvm_ioctl_create_device in virt/kvm/kvm_main.c. A local authenticated attacker could exploit this vulnerability to trigger a use-after-free to crash the guest VM and possibly gain privileged access to a system.
CVSS Base Score: 7.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/157074 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H)
CVEID: CVE-2018-17972
DESCRIPTION: Linux Kernel could allow a local attacker to obtain sensitive information, caused by a flaw in the proc_pid_stack function in fs/proc/base.c. By sending a specially-crafted request, a local attacker could exploit this vulnerability to obtain kernel task stack contents.
CVSS Base Score: 6.2
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/150826 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2018-9568
DESCRIPTION: Google Android could allow a local attacker to gain elevated privileges on the system, caused by a type confusion flaw in the sk_clone_lock function in sock.c. By sending a specially-crafted request, an attacker could exploit this vulnerability to gain elevated privileges.
CVSS Base Score: 8.4
