Use after free in PostgreSQL coordination of anonymous RECORD type identifiers among parallel workers allows a database user to execute arbitrary code as the operating system user running the database, via causing one process to free a shared tuple descriptor while another process retains and later uses its address. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
