Low [CVE-2026-60082] Denial of Service via out-of-bounds read

DBI versions before 1.651 for Perl do not enforce statement handle consistency with the row. When the statement handle had no fields but the source row was non-empty, the internal row-buffer helper would read from a negative array index.

This could be triggered by a caller supplying inconsistent metadata and rows to the prepare method. A flaw was found in perl-DBI, a database interface for Perl.

This vulnerability arises when the DBI library processes inconsistent data, specifically when a statement handle lacks fields but is associated with a non-empty data row. This inconsistency can cause the internal row-buffer to attempt reading from an invalid memory location, an out-of-bounds read.
