Exploitation evidence

Disclosed: evidence found.
CVE published 9 Oct 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade SUSE to 4.18.29.

AI-suggested

Red Hat has released OpenShift Container Platform 4.18.29 containing fixes for these vulnerabilities. Users should upgrade to version 4.18.29 using the OpenShift CLI (oc) or web console as soon as the updated packages and container images are available in their release channel. Detailed upgrade instructions are provided by Red Hat at https://docs.redhat.com/en/documentation/openshift_container_platform/4.18/html-single/updating_clusters/index#updating-cluster-cli. No additional mitigations are indicated by the vendor advisory.

Description

Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. This advisory contains the container images for Red Hat OpenShift Container Platform 4.18.29. See the following advisory for the RPM packages for this release: https://access.redhat.com/errata/156359 Space precludes documenting all of the container images in this advisory. See the following Release Notes documentation, which will be updated shortly for this release, for details about these changes: https://docs.redhat.com/en/documentation/openshift_container_platform/4.18/html/release_notes/ Security Fix(es): * sssd: SSSD default Kerberos configuration allows privilege escalation on AD-joined Linux systems (CVE-2025-11561) * runc: container escape via 'masked path' abuse due to mount race conditions (CVE-2025-31133) * runc: container escape with malicious config due to /dev/console mount and related races (CVE-2025-52565) * runc: opencontainers/selinux: container escape and denial of service due to arbitrary write gadgets and procfs write redirects (CVE-2025-52881) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. To check for available updates, use the OpenShift CLI (oc) or web console. Instructions for upgrading a cluster are available at https://docs.redhat.com/en/documentation/openshift_container_platform/4.18/html-single/updating_clusters/index#updating-cluster-cli.

Impact

The vulnerabilities allow privilege escalation on AD-joined Linux systems (CVE-2025-11561) and container escape attacks (CVE-2025-31133, CVE-2025-52565, CVE-2025-52881), which could compromise container isolation and potentially lead to unauthorized access or denial of service. These issues affect the security boundary of containers and the underlying host systems in OpenShift Container Platform 4.18 prior to 4.18.29.

Summary

This advisory covers security updates in Red Hat OpenShift Container Platform 4.18.29, which address four vulnerabilities: CVE-2025-11561 in sssd allowing privilege escalation on Active Directory-joined Linux systems due to default Kerberos configuration, and three container escape vulnerabilities in runc (CVE-2025-31133, CVE-2025-52565, CVE-2025-52881) caused by mount race conditions, malicious configuration involving /dev/console mounts, and arbitrary write gadgets with procfs write redirects. These vulnerabilities could allow attackers to escalate privileges or escape container isolation. The advisory recommends upgrading to the fixed container images and packages available in OpenShift Container Platform 4.18.29. No CVSS scores are provided in the advisory; however, the severity is rated as important/high by Red Hat.
