6.1 · MEDIUMOverview
CVE-2014-9717 is a medium-severity vulnerability affecting linux linux_kernel. It was published on May 2, 2016 and has a CVSS 3.0 base score of 6.1 (MEDIUM).
This vulnerability has a CVSS 3.0 base score of 6.1, 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 4.0.2 processes MNT_DETACH umount2 system calls without verifying that the MNT_LOCKED flag is unset, which allows local users to bypass intended access restrictions and navigate to filesystem locations beneath a mount by calling umount2 within a user namespace.
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.
