postgresql: PostgreSQL missing validation of multibyte character length executes arbitrary code

Missing validation of multibyte character length in PostgreSQL text manipulation allows a database user to issue crafted queries that achieve a buffer overrun. That suffices to execute arbitrary code as the operating system user running the database...

postgresql: PostgreSQL pgcrypto heap buffer overflow executes arbitrary code

A heap based buffer overflow flaw has been discovered in PostgreSQL. This Heap buffer overflow is in the pgcrypto component and allows a ciphertext provider to execute arbitrary code as the operating system user running the database...

postgresql: PostgreSQL intarray missing validation of type of input to selectivity estimator executes arbitrary code

CVE-2026-6637

Stack buffer overflow in PostgreSQL module "refint" allows an unprivileged database user to execute arbitrary code as the operating system user running the database. A distinct attack is possible if the application declares a user-controlled column as a "refint" cascade primary key and facilitate...

ALPINE-CVE-2026-6473

Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds. This may execute arbitrary code as the operating system user running the database. In applications that pass gigabyte-scale user...

CVE-2026-6637 PostgreSQL refint allows stack buffer overflow and SQL injection

Stack buffer overflow in PostgreSQL module "refint" allows an unprivileged database user to execute arbitrary code as the operating system user running the database. A distinct attack is possible if the application declares a user-controlled column as a "refint" cascade primary key and facilitate...

CVE-2026-6637

The CVE-2026-6637 issue affects PostgreSQL’s refint module, causing a stack buffer overflow that could allow an unprivileged database user to execute arbitrary OS-level code running the database. A separate attack path exists when an application exposes a user-controlled column as a refint cascad...
