DescriptionCVE.org

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.

AnalysisAI

Improper validation of the "oidvector" type in PostgreSQL allows authenticated database users to read small amounts of server memory, potentially exposing sensitive data. This vulnerability affects PostgreSQL versions prior to 18.2, 17.8, 16.12, 15.16, and 14.21, with no patch currently available for impacted systems.
