Vulnerability Details

Summary

Intel® Manycore Platform Software Stack (Intel® MPSS) for Linux and Windows have addressed the following vulnerabilities in Linux Kernel.

Vulnerability Details

CVEID: CVE-2017-17450

Description: Linux Kernel could allow a local attacker to bypass security restrictions, caused by the failure to require the CAP_NET_ADMIN capability for add_callback and remove_callback operations in net/netfilter/xt_osf.c. By sending a specially-crafted request, an attacker could exploit this vulnerability to bypass intended access restrictions.

CVSS Base Score: 6.2
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/136107&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N)

CVEID: CVE-2017-17052

Description: Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a use-after-free in the mm_init function in kernel/fork.c. 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/135701&gt; 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:H/A:H)

CVEID: CVE-2017-15951

Description: Linux Kernel is vulnerable to a denial of service, caused by a race condition in the KEYS subsystem. By using specially-crafted system calls, a local authenticated attacker could exploit this vulnerability to cause a denial of service condition.

CVSS Base Score: 5.5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/134189&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2017-15115

Description: Linux Kernel is vulnerable to a denial of service, caused by a use-after-free in the sctp_do_peeloff function in net/sctp/socket.c. By using specially-crafted system calls, 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/135068&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2017-8824

Description: Linux Kernel could allow a local attacker to gain elevated privileges on the system, caused by a use-after-free in the dccp_disconnect function in net/dccp/proto.c. By using a specially-crafted system call, an attacker could exploit this vulnerability to gain privileges or cause a denial of service.

CVSS Base Score: 5.9
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/135913&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)
