Hi, The following vulnerability was published for libxml-libxml-perl. CVE-2026-8177[0]: | XML::LibXML versions through 2.0210 for Perl read out-of-bounds heap | memory when parsing XML node names containing truncated UTF-8 byte | sequences. A node name ending in the middle of a multi byte UTF-8 | sequence causes the parser to read past the end of the input string | into adjacent heap memory. Any Perl process that passes attacker | controlled strings to XML::LibXML's DOM node-name methods can reach | this path on the default API. The likely consequence is a crash, | causing denial of service. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
