Improper locking in PostgreSQL startup processing allows an unauthenticated network client to trigger a server restart, via arranging for authentication_timeout to arrive while it holds a spinlock during cancel handling. Within major version 18, minor versions before PostgreSQL 18.7 are affected. Versions before PostgreSQL 18 are unaffected.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
