CVE-2026-14679 is a stack-based buffer overflow in PostgreSQL server argument-name matching. An object creator can trigger out-of-bounds writes to stack memory by manipulating the number of OUT parameters. The corruption primitive is constrained to writing zero and one byte values, respectively; the ultimate security impact has not been established.
