+    CVE-2025-32415

+  description: |
+    ## Summary
+
+    Nokogiri v1.18.8 upgrades its dependency libxml2 to
+    [v2.13.8](https://gitlab.gnome.org/GNOME/libxml2/-/releases/v2.13.8).
+
+    libxml2 v2.13.8 addresses:
+
+    - CVE-2025-32414
+      - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/889
+    - CVE-2025-32415
+      - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/890
+
+    ## Impact
+
+    ### CVE-2025-32414: No impact
+
+    In libxml2 before 2.13.8 and 2.14.x before 2.14.2, out-of-bounds
+    memory access can occur in the Python API (Python bindings) because
+    of an incorrect return value. This occurs in xmlPythonFileRead and
+    xmlPythonFileReadRaw because of a difference between bytes and characters.
+
+    **There is no impact** from this CVE for Nokogiri users.
+
+    ### CVE-2025-32415: Low impact
+
+    In libxml2 before 2.13.8 and 2.14.x before 2.14.2,
+    xmlSchemaIDCFillNodeTables in xmlschemas.c has a heap-based buffer
+    under-read. To exploit this, a crafted XML document must be validated
+    against an XML schema with certain identity constraints, or a
+    crafted XML schema must be used.
+
+    In the upstream issue, further context is provided by the maintainer:
+
+    > The bug affects validation against untrusted XML Schemas (.xsd)
+    > and validation of untrusted documents against trusted Schemas if
+    > they make use of xsd:keyref in combination with recursively
+    > defined types that have additional identity constraints.
+
+    MITRE has published a severity score of 2.9 LOW
+    (CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L) for this CVE.
