When creating or opening a database table in the DBD::DBM module fails due to an error, an exclusive file lock acquired during initialization is not properly released. A user or attacker who can control connection parameters can trigger this failure, leaving the lock active indefinitely. This issue leads to a Denial of Service (DoS), as subsequent attempts by any process to access the affected table will hang permanently.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9 · no fix planned: Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, … · updated 2026-10-21 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-111879.json)\n\n**perl-DBI: perl-DBI: Denial of Service via unreleased table lock on error** — rated Moderate by Red Hat.
