CVE-2019-14891 (GCVE-0-2019-14891)

Vulnerability from cvelistv5 – Published: 2019-11-25 10:31 – Updated: 2024-08-05 00:26

Summary

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.

Severity

5 (Medium)
