An integer (IV) or floating-point (NV) value has no valid string pointer, so grok_number reads from an invalid address, triggering a segmentation fault.\n\nThis is reachable in Perl using the sql_type_cast function:\n\n  my $num = 42;\n  DBI::sql_type_cast( $num, DBI::SQL_NUMERIC, 0 );","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-843"],"vendors":[],"products":[],"references":[{"url":"https://github.com/perl5-dbi/dbi/commit/e5ad87e5602da995d28b4d65df222368b58d6702.patch","tags":[]},{"url":"https://github.com/perl5-dbi/dbi/security/advisories/GHSA-c8vq-w3wr-6979","tags":[]},{"url":"https://metacpan.org/release/HMBRAND/DBI-1.654/changes","tags":[]},{"url":"http://www.openwall.com/lists/oss-security/2026/09/28/12","tags":[]}],"exploitRefs":[{"url":"https://github.com/perl5-dbi/dbi/commit/e5ad87e5602da995d28b4d65df222368b58d6702.patch","tags":[]},{"url":"https://github.com/perl5-dbi/dbi/security/advisories/GHSA-c8vq-w3wr-6979","tags":[]}],"hasPoc":true,"ai":null}
