CVE-2026-17113CVE-2026-17113
Description
A flaw was found in CRI-O's container-creation environment-variable handling
(`mergeEnvs` in `server/utils.go`, consumed by `setupContainerEnvironmentAndWorkdir` in
`server/container_create.go`). When a `CreateContainer` request supplies a `nil` CRI
`Envs` field, CRI-O falls back to using the target OCI image's `config.Env` entries
unfiltered, in contrast to the normal merge path, which validates each entry for a
`key=value` form before use. An OCI image whose `config.Env` contains an entry with no
`=` character (e.g. a bare `NOEQUALS` string) causes CRI-O to split that entry into a
single-element slice and then index its second element, which is out of range. This
triggers an unrecovered Go runtime panic in the `crio` daemon process, crashing it and
terminating the container-runtime service for all workloads on the node until it is
restarted.
