CVE-2026-90775
PostGIS address_standardizer through 3.7.0 fails to validate the Weight parameter from caller-supplied rules tables before using it as an array index. Attackers can craft malicious rule rows with out-of-range Weight values to trigger out-of-bounds reads in the load_value array, causing the PostgreSQL backend process to crash and terminate all cluster sessions.
