{"id":"DEBIAN-CVE-2026-88815","details":"DBI versions before 1.654 for Perl incorrectly treat numeric values as strings in sql_type_cast_svpv.  When casting to SQL_NUMERIC, sql_type_cast_svpv passes the string pointer and length of the SV to grok_number without stringifying it first. 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.  This is reachable in Perl using the sql_type_cast function:    my $num = 42;   DBI::sql_type_cast( $num, DBI::SQL_NUMERIC, 0 );","modified":"2026-09-29T05:00:56.697676615Z","published":"2026-09-28T17:17:52.070Z","upstream":["CVE-2026-88815"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-88815"}],"affected":[{"package":{"name":"libdbi-perl","ecosystem":"Debian:12","purl":"pkg:deb/debian/libdbi-perl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.643-4+deb12u3"}]}],"versions":["1.643-4","1.643-4+deb12u1","1.643-4+deb12u2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88815.json"}},{"package":{"name":"libdbi-perl","ecosystem":"Debian:13","purl":"pkg:deb/debian/libdbi-perl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.647-1","1.647-1+deb13u1","1.648-1","1.649-1","1.650-1","1.651-1","1.652-1","1.652-2","1.652-2~deb13u1","1.653-1","1.654-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88815.json"}},{"package":{"name":"libdbi-perl","ecosystem":"Debian:14","purl":"pkg:deb/debian/libdbi-perl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.647-1","1.648-1","1.649-1","1.650-1","1.651-1","1.652-1","1.652-2","1.652-2~deb13u1","1.653-1","1.654-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88815.json"}}],"schema_version":"1.9.0"}
