For a field of only blanks it reads the byte before the field's heap buffer. If that byte is also a space or tab, it may be zeroed and the walk continue backwards, depending on what the allocator placed there.\n\nLeading blanks are normally skipped before a field is stored, but an all-blank field still arrives after a leading escape_char that differs from quote_char, or as a quoted field in getline when its line ends in two CRs.\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-2026-110758.json)","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[{"seq":226082,"id":"CVE-2026-110758","ts":1792523847446,"field":"cvss","old":"5.9","new":"7.5"},{"seq":226081,"id":"CVE-2026-110758","ts":1792523847446,"field":"severity","old":"medium","new":"high"},{"seq":223705,"id":"CVE-2026-110758","ts":1792238372493,"field":"cvss","old":null,"new":"5.9"},{"seq":223704,"id":"CVE-2026-110758","ts":1792238372493,"field":"severity","old":"none","new":"medium"}]}
