CVE-2016-6213
4.7 · MEDIUMOverview
CVE-2016-6213 is a medium-severity vulnerability affecting linux linux_kernel. It was published on December 28, 2016 and has a CVSS 3.0 base score of 4.7 (MEDIUM).
This vulnerability has a CVSS 3.0 base score of 4.7, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
fs/namespace.c in the Linux kernel before 4.9 does not restrict how many mounts may exist in a mount namespace, which allows local users to cause a denial of service (memory consumption and deadlock) via MS_BIND mount system calls, as demonstrated by a loop that triggers exponential growth in the number of mounts.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
