FKIE_CVE-2026-7111

Vulnerability from fkie_nvd - Published: 2026-04-29 15:16 - Updated: 2026-05-06 16:16
Severity
8.4 (High) - CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
Text::CSV_XS versions before 1.62 for Perl have a use-after-free when registered callbacks extend the Perl argument stack, which may enable type confusion or memory corruption. The Parse, print, getline, and getline_all methods invoke registered callbacks (for example after_parse, before_print, or on_error) and cache the Perl argument stack pointer across the call. If a callback extends the argument stack enough to trigger a reallocation, the return value is written through the stale pointer into the freed buffer, and the caller reads the original $self argument as the return value instead. Calling code that expects parsed data from getline_all receives the Text::CSV_XS object in its place, leading to logic errors or crashes. Text::CSV_XS objects used without any registered callbacks are not affected.
