This issue was patched in RHSA-2025:12450.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libxml2-devel package and not the libxml2-devel package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

A flaw was found in libxslt where the attribute type, atype, flags are modified in a way that corrupts internal memory management. When XSLT functions, such as the key() process, result in tree fragments, this corruption prevents the proper cleanup of ID attributes. As a result, the system may access freed memory, causing crashes or enabling attackers to trigger heap corruption.
