CVE-2025-12863

Name of the Vulnerable Software and Affected Versions libxml2 (affected versions not specified)

Description A flaw exists in the xmlSetTreeDoc() function of the libxml2 XML parsing library. This function manages document pointers during XML node movements between documents. Improper handling of namespace references can result in a namespace pointer remaining linked to a freed memory region after the original document is destroyed. Subsequent access to this namespace can trigger a use-after-free condition, potentially leading to application crashes.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
