CVE-2026-90775: Out-of-bounds Read in PostGIS address_standardizer
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.
AI Analysis
Technical Summary
PostGIS address_standardizer versions through 3.7.0 do not validate the Weight parameter from user-supplied rules tables before using it as an array index. Maliciously crafted rule rows with out-of-range Weight values can trigger out-of-bounds reads in the load_value array. This results in a crash of the PostgreSQL backend process, causing termination of all cluster sessions.
Potential Impact
Successful exploitation causes the PostgreSQL backend process to crash, leading to denial of service by terminating all cluster sessions. There is no indication of data corruption or privilege escalation from the provided information.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
