———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.

due to improper handling of Modbus TCP request data. A remote,
unauthenticated attacker with access to the affected service could
trigger a heap-based buffer overflow, resulting in a denial of service.1dCVE-2026-196944.7 MED0.9%

——9An application using the MongoDB BI Connector ODBC Driver may experience a memory-safety issue when processing output parameters from a stored procedure. Triggering this issue requires connecting to an untrusted or impersonated database server that returns crafted metadata. This may result in process termination, disclosure of process memory, or, under certain conditions, arbitrary code execution.1d
