Only the syntax and order of the ranges are checked, so row=1-400000000 on a two-line file allocates 400 million elements.\n\nAn application that passes a request-supplied fragment to fragment or csv can be made to exhaust memory, which ends the process with an Out of memory error that eval cannot catch.\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** · Important · 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-2026-110752.json)","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[{"seq":223717,"id":"CVE-2026-110752","ts":1792238375643,"field":"cvss","old":null,"new":"7.5"},{"seq":223716,"id":"CVE-2026-110752","ts":1792238375643,"field":"severity","old":"none","new":"high"}]}
