Answer in brief
CVE-2026-110756 records a Unknown severity vulnerability in Text::CSV_XS versions before 1.65 for Perl drop the end of a record and its line ending when a UTF-8 flagged field precedes invalid UTF-8 bytes in print. The current sources do not mark it as known exploited. The current feed maps Text-CSV_XS (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Text::CSV_XS versions before 1.65 for Perl drop the end of a record and its line ending when a UTF-8 flagged field precedes invalid UTF-8 bytes in print. When a record contains a UTF-8 flagged field, print holds back trailing bytes that are not valid UTF-8 at each buffer flush, so that a character split across two flushes can be completed. Nothing writes the held-back bytes after the record's final flush. A record whose last field ends in such a byte loses it, any closing quote and the line ending, while print still returns true. combine is not affected. The next record is written onto the same line, or, when the last field was quoted, the missing closing quote makes a reader take every following record as part of that field.
