CVE-2026-112048

libspatialite through 5.1.0 Uncontrolled Memory Allocation via ParseWkbPolygon Ring Count

6.9 Medium

libspatialite through 5.1.0 fails to validate the polygon ring count in ParseWkbPolygon, allowing attackers to trigger uncontrolled interior-ring allocation via crafted geometry BLOBs. Attackers can supply a crafted polygon in a SpatiaLite database or ST_GeomFromWKB input to crash the process or corrupt heap memory on 32-bit builds.
