CVE-2026-14740

A flaw was found in DBI for Perl. When processing SQL queries, the preparse method, which normalizes SQL and removes comments, can read one byte beyond its intended memory boundary. This occurs specifically when an SQL query begins with a comment line, leading to an out-of-bounds read during the comment deletion process. This issue may cause a program fault on systems with memory hardening or result in unpredictable newline retention in other environments.
