CVE-2026-110753

Text::CSV XS versions from 1.46 before 1.65 for Perl have a use-after-free of bind columns variables when skip empty rows skips an empty line in getline.

With bind columns, the parser writes each field into the caller's own scalar without taking a reference to it. When skip empty rows skips an empty last line, the parser frees the current field scalar without checking whether it is bound, dropping one reference from the application's variable. The "eof" mode does the same on any empty line.

The variable is then freed while the application still references it, so later code uses freed memory and can crash the process.
