NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql-server package and not the postgresql-server package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

Heap buffer overflow in PostgreSQL regexp allows the query author to execute arbitrary code as the operating system user running the database, via text that would not pass encoding validation. This shares heritage with CVE-2026-2006, but this case involved unanticipated data growth when round-tripped through pg_wchar. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
