Summary
containerd CRI server: Host memory exhaustion through Attach goroutine leak
Details

Impact

A bug was found in containerd's CRI Attach implementation where a user can exhaust memory on the host due to goroutine leaks.

Repetitive calls of CRI Attach (e.g., <code>kubectl attach</code>) could increase the memory usage of containerd.

Patches

This bug has been fixed in the following containerd versions:

  • 2.2.0
  • 2.1.5
  • 2.0.7
  • 1.7.29

Users should update to these versions to resolve the issue.

Workarounds

Set up an admission controller to control accesses to pods/attach resources. e.g., Validating Admission Policy.
