CVE-2026-111879: DBI versions before 1.656 for Perl hang on a later open of a DBD::DBM table because a failed open_data does not release the table's lock

A vulnerability in Perl's DBI module before version 1.656 causes the application to hang when attempting to open a DBD::DBM table following a failed initial open, because the failed operation does not release the table's lock. The issue affects DBD::DBM table operations specifically.

Why it matters: Perl developers using DBI versions before 1.656 with DBD::DBM tables face denial of service risk if table opens fail; upgrade to 1.656 or later to resolve the hanging condition.
