Process crash via negative row-buffer index
Published Jul 14, 2026 · Updated Jul 14, 2026
Out-of-bounds read in DBI before 1.651 allows attackers to crash a Perl process through inconsistent statement metadata and row data. The DBI.xs _set_fbav helper starts its resize loop at index -1 when a zero-field statement buffer receives a non-empty row, so sv_setsv reads a pointer before the array. Reachability requires control of both field metadata and row width; ordinary SQL does not trigger the fault, but a malicious DBI::Gofer or ProxyServer peer can supply the mismatch.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
