CVE-2026-112048 PUBLISHED

libspatialite through 5.1.0 Uncontrolled Memory Allocation via ParseWkbPolygon Ring Count

Assigner: VulnCheck
Reserved: 18.10.2026 Published: 18.10.2026 Updated: 18.10.2026

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.
