#VU39739 Resource management error in Linux kernel - CVE-2016-10153

Vulnerability identifier: #VU39739

Vulnerability risk: Low

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2016-10153

CWE-ID: CWE-399

Exploitation vector: Local

Exploit availability: No

Vulnerable software:
Linux kernel
Operating systems & Components / Operating system

Vendor: Linux Foundation

Description

The vulnerability allows a local authenticated user to execute arbitrary code.

The crypto scatterlist API in the Linux kernel 4.9.x before 4.9.6 interacts incorrectly with the CONFIG_VMAP_STACK option, which allows local users to cause a denial of service (system crash or memory corruption) or possibly have unspecified other impact by leveraging reliance on earlier net/ceph/crypto.c code.

Mitigation
Install update from vendor's website.

Vulnerable software versions

Linux kernel: 4.9 - 4.9.5
