5.5 · MEDIUM
Published Apr 5, 2017 linux EPSS 1.46% (72th pctl)

Overview

CVE-2017-2671 is a medium-severity vulnerability affecting linux linux_kernel. It was published on April 5, 2017 and has a CVSS 3.0 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.0 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

The ping_unhash function in net/ipv4/ping.c in the Linux kernel through 4.10.8 is too late in obtaining a certain lock and consequently cannot ensure that disconnect function calls are safe, which allows local users to cause a denial of service (panic) by leveraging access to the protocol value of IPPROTO_ICMP in a socket system call.

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.
