Detailsinfo

A vulnerability, which was classified as problematic, was found in xmlsoft libxml2 up to 2.13.7/2.14.1. This affects the function xmlSchemaIDCFillNodeTables of the file xmlschemas.c of the component XML Document Handler. The manipulation with an unknown input leads to a improper validation of specified quantity in input vulnerability. CWE is classifying the issue as CWE-1284. The product receives input that is expected to specify a quantity (such as size or length), but it does not validate or incorrectly validates that the quantity has the required properties. This is going to have an impact on availability. The summary by CVE is:

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.

It is possible to read the advisory at gitlab.gnome.org. This vulnerability is uniquely identified as CVE-2025-32415 since 04/08/2025. The exploitability is told to be difficult. Attacking locally is a requirement. Technical details of the vulnerability are known, but there is no available exploit.
