CVE-2026-8177 not yet assigned priority: Debian including 1 source packages (libxml-libxml-perl), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 4, open 1.
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.
