Upgrade RHEL:10 libxslt to version 0:1.1.39-8.el10_0 or higher.
This issue was patched in RHBA-2025:12345.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libxslt package and not the libxslt package as distributed by RHEL. See How to fix? for RHEL:10 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.
