Exploitation evidence

Disclosed: evidence found.
CVE published 10 Jul 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 libxml2 and the Debian debian/libxml2 package to 2.15.2.

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 4.19.10. See the following advisory for the RPM packages for this release: https://access.redhat.com/errata/RHBA-2025:14817 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/4.19/html/release_notes/ Security Fix(es): * libxslt: Heap Use-After-Free in libxslt caused by atype corruption in xmlAttrPtr (CVE-2025-7425) * libxml2: Out-of-Bounds Read in libxml2 (CVE-2025-32414) * libxml2: Out-of-bounds Read in xmlSchemaIDCFillNodeTables (CVE-2025-32415) 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/4.19/html-single/updating_clusters/index#updating-cluster-cli.

Impact

The vulnerabilities include a heap use-after-free and out-of-bounds reads, which can cause memory corruption or potentially expose sensitive information. The security impact is rated as Important by Red Hat Product Security. No known exploits in the wild have been reported at this time. The issues affect OpenShift Container Platform 4.19 deployments prior to 4.19.10.

Summary

This advisory covers security updates in Red Hat OpenShift Container Platform 4.19.10 that fix three vulnerabilities: CVE-2025-7425, a heap use-after-free in libxslt caused by atype corruption in xmlAttrPtr; CVE-2025-32414, an out-of-bounds read in libxml2; and CVE-2025-32415, an out-of-bounds read in xmlSchemaIDCFillNodeTables within libxml2. These vulnerabilities could lead to memory corruption or information disclosure. The update is delivered as container images and RPM packages for OpenShift Container Platform 4.19. Users should upgrade using the OpenShift CLI or web console following Red Hat's documented procedures.

CWE-416Use After Free (opens in a new tab)
Variant weaknessLikelihood of exploit: HighCWE Top 25 (2025): #7
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
Architecture and Design · Language Selection
Choose a language that provides automatic memory management.
Implementation · Attack Surface Reduction
When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.

CWE-393Return of Wrong Status Code (opens in a new tab)
Base weakness
A function or operation returns an incorrect return value or status code that does not indicate the true result of execution, causing the product to modify its behavior based on the incorrect result.
CWE-125Out-of-bounds Read (opens in a new tab)
Base weaknessCWE Top 25 (2025): #8
The product reads data past the end, or before the beginning, of the intended buffer.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design · Language Selection
Use a language that provides appropriate memory abstractions.
