NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql:16/pgvector package and not the postgresql:16/pgvector package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

Improper validation of type "oidvector" in PostgreSQL allows a database user to disclose a few bytes of server memory. We have not ruled out viability of attacks that arrange for presence of confidential information in disclosed bytes, but they seem unlikely. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected.
