Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability was found in CRI-O that causes memory or disk space exhaustion on the node for anyone with access to the Kube API. The ExecSync request runs commands in a container and logs the output of the command. This output is then read by CRI-O after command execution, and it is read in a manner where the entire file corresponding to the output of the command is read in. Thus, if the output of the command is large it is possible to exhaust the memory or the disk space of the node when CRI-O reads the output of the command. The highest threat from this vulnerability is system availability.

dbcve analysis
How this class of weakness works · CWE-400

A single request can consume unbounded CPU, memory, or connections, so a modest amount of malicious traffic exhausts the service. The result is denial of service for everyone else. Remediation is enforcing limits, quotas, and timeouts on what any one request can use.

Recommended fix High confidence

Upgrade to CRI-O 1.19.7, 1.20.8, 1.21.8, or 1.22.5 (or later) depending on your current branch

  1. Identify the currently installed CRI-O version using: `crio --version` or `rpm -q cri-o`
  2. For Cri-O, upgrade to version 1.19.7 or later if previously < 1.19.7
  3. For Cri-O >= 1.20.0, upgrade to version 1.20.8 or later
  4. For Cri-O >= 1.21.0, upgrade to version 1.21.8 or later
  5. For Cri-O >= 1.22.0, upgrade to version 1.22.5 or later
  6. After upgrade, restart the CRI-O service: `systemctl restart crio`
  7. Verify the new version is running: `crio --version`
  8. For OpenShift Container Platform deployments, apply the corresponding errata or upgrade via OpenShift update path to a version containing the CRI-O fix
Caveat Minor: Ensure container workloads are not disrupted during CRI-O service restart; verify compatibility with your Kubernetes version
