When a `CreateContainer` request supplies a `nil` CRI\n`Envs` field, CRI-O falls back to using the target OCI image's `config.Env` entries\nunfiltered, in contrast to the normal merge path, which validates each entry for a\n`key=value` form before use. An OCI image whose `config.Env` contains an entry with no\n`=` character (e.g. a bare `NOEQUALS` string) causes CRI-O to split that entry into a\nsingle-element slice and then index its second element, which is out of range. This\ntriggers an unrecovered Go runtime panic in the `crio` daemon process, crashing it and\nterminating the container-runtime service for all workloads on the node until it is\nrestarted."
