Vulnerability Details

Relevant CVE Information:

CVEID: CVE-2018-1000004
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by a race condition in the sound system. A remote attacker could exploit this vulnerability to cause the system to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/137756 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2018-6927
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by an integer overflow in the futex_requeue function in kernel/futex.c. By triggering a negative wake or requeue value, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base Score: 7.5

CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2017-1000407
DESCRIPTION: Linux Kernel, built with the KVM virtualization(CONFIG_KVM) support, is vulnerable to a denial of service, caused by improper validation of user-supplied input at the diagnostic port. By flooding the diagnostic port 0x80, a remote authenticated attacker could exploit this vulnerability to cause the system to crash.

CVEID: CVE-2017-18017
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by a use-after-free flaw in the tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c. By leveraging the presence of xt_TCPMSS in an iptables action, a remote attacker could exploit this vulnerability to cause a denial of service condition.

CVEID: CVE-2017-15126
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by a use-after-free flaw in fs/userfaultfd.c. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause fork event to be removed from an already freed list.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/137626 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2017-15116
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by NULL pointer dereference in the rngapi_reset function in crypto/rng.c. By sending a specially-crafted packet, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/135735 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2016-8633
DESCRIPTION: Linux Kernel could allow a remote attacker to execute arbitrary code on the system, caused by an error in drivers/firewire/net.c. By sending specially-crafted fragmented packets. An attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base Score: 7.3

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)

CVEID: CVE-2017-1000410
DESCRIPTION: Linux Kernel could allow a remote attacker to obtain sensitive information, caused by a flaw when processing the incoming of L2CAP commands, ConfigRequest and ConfigResponse messages. By manipulating the code flows that precede the handling of the configuration messages, a remote attacker could exploit this vulnerability to obtain sensitive information.
