MediumCVSS 6.5/10Last modified Nov 12, 2026

Description

Buffer over-read in PostgreSQL parallel B-tree scans allows an object creator to read attacker-chosen server-memory addresses, via a function incorrectly marked PARALLEL SAFE or STABLE to make participating workers build different scan-key arrays. Within major versions 17-18, minor versions before PostgreSQL 18.7 and 17.12 are affected. Versions before PostgreSQL 17 are unaffected.
