Description Siddharth Sharma 2026-08-25 14:38:31 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

A flaw was found in CRI-O, the container runtime. Under a specific internal condition, CRI-O skips checking whether a container image's environment variable settings are properly formatted before using them. If an image contains a malformed environment variable, CRI-O crashes while trying to process it.
