CVE-2022-0811· NVD / CVE Program· CNA redhat

A flaw was found in CRI-O in the way it set kernel options for a pod.

Noroxi assessment

Priority: Plan (action score 41/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 19% (FIRST EPSS); higher than 97.2% 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. No special conditions are required; it is repeatable.
  • Fixed version: github.com/cri-o/cri-o (Go) 1.19.6, 1.20.7, 1.21.6; cri-o (Red Hat:openshift:4.10::el7) 0:1.23.1-12.rhaos4.10.git1607c6e.el7; cri-o-debuginfo (Red Hat:openshift:4.10::el7) 0:1.23.1-12.rhaos4.10.git1607c6e.el7.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Add it to your regular patch cycle. Upgrade to github.com/cri-o/cri-o (Go) 1.19.6, 1.20.7, 1.21.6; cri-o (Red Hat:openshift:4.10::el7) 0:1.23.1-12.rhaos4.10.git1607c6e.el7; cri-o-debuginfo (Red Hat:openshift:4.10::el7) 0:1.23.1-12.rhaos4.10.git1607c6e.el7 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw was found in CRI-O in the way it set kernel options for a pod. This issue allows anyone with rights to deploy a pod on a Kubernetes cluster that uses the CRI-O runtime to achieve a container escape and arbitrary code execution as root on the cluster node, where the malicious pod was deployed.

Affected versions

NVD version ranges (for catalog products). Add the product to your stack with a version and matching uses these.

  • kubernetes cri-o1.19.0 and later · before 1.19.6
  • kubernetes cri-o1.20.0 and later · before 1.20.7
  • kubernetes cri-o1.21.0 and later · before 1.21.6
  • kubernetes cri-o1.22.0 and later · before 1.22.3
  • kubernetes cri-o1.23.0 and later · before 1.23.2

Versions reported by the vendor

Affected version ranges reported by the assigning authority (redhat). Independent of NVD's CPE analysis and usually ahead of it.
