CVE-2019-14891: A flaw was found in cri-o, as a result of all pod-related processes being placed in the same memory cgroup.

Noroxi assessment

Priority: Monitor (action score 20/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.79% (FIRST EPSS); higher than 56.7% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: atomic-openshift (Red Hat:openshift:3.11::el7) 0:3.11.248-1.git.0.92ee8ac.el7; atomic-openshift-clients (Red Hat:openshift:3.11::el7) 0:3.11.248-1.git.0.92ee8ac.el7; atomic-openshift-clients-redistributable (Red Hat:openshift:3.11::el7) 0:3.11.248-1.git.0.92ee8ac.el7.

Low priority for now. Upgrade to atomic-openshift (Red Hat:openshift:3.11::el7) 0:3.11.248-1.git.0.92ee8ac.el7; atomic-openshift-clients (Red Hat:openshift:3.11::el7) 0:3.11.248-1.git.0.92ee8ac.el7; atomic-openshift-clients-redistributable (Red Hat:openshift:3.11::el7) 0:3.11.248-1.git.0.92ee8ac.el7 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw was found in cri-o, as a result of all pod-related processes being placed in the same memory cgroup. This can result in container management (conmon) processes being killed if a workload process triggers an out-of-memory (OOM) condition for the cgroup. An attacker could abuse this flaw to get host network access on an cri-o host.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
