A security update addresses CVE-2026-8177 in perl-XML-LibXML, which involves a read out-of-bounds heap memory issue triggered by parsing XML node names containing truncated UTF-8 byte sequences. This vulnerability can cause a denial of service. The issue affects multiple versions of perl-XML-LibXML used in SUSE and Red Hat Enterprise Linux 9 distributions. An official fix is available and has been released by Red Hat and SUSE.

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.
