CVE-2026-8177 on CTRL-OS 26.05

Aliases: CVE-2026-8177

Packages: perlPackages.XMLLibXML

Status: Plausible

Advisory Information

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.
