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."}], "affected": [{"vendor": "Red Hat", "product": "Red Hat OpenShift Container Platform 4", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "cri-o", "defaultStatus": "affected", "cpes": ["cpe:/a:redhat:openshift:4"]}, {"vendor": "Red Hat", "product": "Red Hat OpenShift Container Platform 4", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "openshift/ose-rhel-coreos-8", "defaultStatus": "affected", "cpes": ["cpe:/a:redhat:openshift:4"]}, {"vendor": "Red Hat", "product": "Red Hat OpenShift Container Platform 4", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "openshift/ose-rhel-coreos-9", "defaultStatus": "affected", "cpes": ["cpe:/a:redhat:openshift:4"]}, {"vendor": "Red Hat", "product": "Red Hat OpenShift Container Platform 4", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "rhcos", "defaultStatus": "affected", "cpes": ["cpe:/a:redhat:openshift:4"]}], "references": [{"url": "https://access.redhat.com/security/cve/CVE-2026-17113", "tags": ["vdb-entry", "x_refsource_REDHAT"]}, {"url": "https://bugzilla.redhat.com/show_bug.cgi?id=2506872", "name": "RHBZ#2506872", "tags": ["issue-tracking", "x_refsource_REDHAT"]}], "datePublic": "2026-08-24T20:52:00.000Z", "problemTypes": [{"descriptions": [{"cweId": "CWE-1287", "description": "Improper Validation of Specified Type of Input", "lang": "en", "type": "CWE"}]}], "x_redhatCweChain": "CWE-1287: Improper Validation of Specified Type of Input", "timeline": [{"lang": "en", "time": "2026-07-19T00:00:00.000Z", "value": "Reported to Red Hat."}, {"lang": "en", "time": "2026-08-24T20:52:00.000Z", "value": "Made public."}], "credits": [{"lang": "en", "value": "Red Hat would like to thank Arpit Jain for reporting this issue."}], "providerMetadata": {"orgId": "53f830b8-0a3f-465b-8143-3b8a9948e749", "shortName": "redhat", "dateUpdated": "2026-08-24T21:36:12.479Z"}, "x_generator": {"engine": "cvelib 1.8.0"}}}}
