With binary set, parse(\"a,\\r\") returns the fields \"a\" and \"\\xFF\". On UTF-8 flagged input the last field is a UTF-8 flagged string holding that lone byte, which is malformed UTF-8. The same input with a non-empty last field is rejected as an error.\n\nA CRLF file read line by line and chomped ends this way when its last column is empty, so the application receives a byte that is not in its input.\n\n## Affected\n\n- `Text-CSV_XS < 1.65`\n\n## Remediation\n\nUpgrade to Text-CSV_XS 1.65 or later.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 9 · no fix planned: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 9 · updated 2026-10-19 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-110759.json)","depth":"midnight","depthScore":54,"depthScoreParts":{"impact":53.9,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[{"seq":226076,"id":"CVE-2026-110759","ts":1792523828771,"field":"cvss","old":"6.5","new":"9.8"},{"seq":226075,"id":"CVE-2026-110759","ts":1792523828771,"field":"severity","old":"medium","new":"critical"},{"seq":223701,"id":"CVE-2026-110759","ts":1792238371741,"field":"cvss","old":null,"new":"6.5"},{"seq":223700,"id":"CVE-2026-110759","ts":1792238371741,"field":"severity","old":"none","new":"medium"}]}
