  "details": "### Impact\n`DNSIncoming._log_exception_debug` and the four `QuietLogger` exception-dedup methods stored an unbounded `_seen_logs` dict keyed by `str(sys.exc_info()[1])`. The seven `IncomingDecodeError` messages raised from `_read_name` / `_decode_labels_at_offset` (RFC 6762 \u00a718 name-decoding error paths) all embed `self.source` \u2014 the peer\u0027s ephemeral source port, varying per packet \u2014 plus byte `offset` and pointer `link`, so every attacker-influenced combination produced a fresh dedup key. The stored value was the full `sys.exc_info()` triple, whose traceback\u0027s frame locals retained `self.data` (the raw inbound packet, up to 8966 bytes per RFC 6762 \u00a717). Each unique malformed packet therefore pinned ~9 KB until process exit.\n\nAny unauthenticated host on the local link (UDP/5353, `224.0.0.251` / `ff02::fb`) can drive memory growth at line rate; that includes a guest on the same Wi-Fi, a compromised IoT device, or a container on a shared bridge. On memory-constrained deployments (Home Assistant on Raspberry-Pi-class hardware is the canonical victim) sustained traffic trivially OOM-kills the process, and mDNS-dependent features (HomeKit, Chromecast/Matter, AirPlay, printers) degrade or fail.\n\n### Patches\nFixed in `zeroconf` 0.149.6 ([PR #1717](https://github.com/python-zeroconf/python-zeroconf/pull/1717)). Upgrade to `\u003e= 0.149.6`.\n\n### Workarounds\nThere is no in-process workaround; upgrading is the fix. Otherwise, restrict mDNS (UDP/5353) to trusted Layer-2 segments via AP client isolation, guest-network separation, or host firewall rules.\n\n### Resources\n- [PR #1717](https://github.com/python-zeroconf/python-zeroconf/pull/1717), fix\n- [Issue #1714](https://github.com/python-zeroconf/python-zeroconf/issues/1714), public tracking issue\n- [RFC 6762 \u00a717](https://www.rfc-editor.org/rfc/rfc6762#section-17), [RFC 6762 \u00a718](https://www.rfc-editor.org/rfc/rfc6762#section-18), [CWE-400](https://cwe.mitre.org/data/definitions/400.html)",

Users are recommended to upgrade to version 3.2.3, which fixes this issue by imposing a default maximum size on data read from remote policy references.",
