CVE-2026-47180

Zeroconf is a pure Python implementation of multicast DNS service discovery. Prior to 0.149.5, DNSIncoming.decodelabelsatoffset recurses once per DNS-name compression pointer, and a single mDNS packet carrying chained pointers can trigger a RecursionError that escapes DNSIncoming.init, causing...

CVE-2026-47180 Zeroconf: Unbounded recursion in DNS compression-pointer decoder allows LAN-local denial of service

Zeroconf is a pure Python implementation of multicast DNS service discovery. Prior to 0.149.5, DNSIncoming.decodelabelsatoffset recurses once per DNS-name compression pointer, and a single mDNS packet carrying chained pointers can trigger a RecursionError that escapes DNSIncoming.init, causing...

CVE-2026-47180

CVE-2026-47180 affects the Zeroconf Python library. The vulnerability stems from DNSIncoming._decode_labels_at_offset recursing for each DNS-name compression pointer; a crafted mDNS packet with ~1500 chained pointers can cause unbounded recursion, escaping DNSIncoming.init and triggering sustaine...

CVE-2026-40007 affects Apache IoTDB. The issue is an uncontrolled recursion in the AirGap receiver: when pipe_air_gap_receiver_enabled is true, readLength recursively processes E-language prefixes with no depth limit, allowing an unauthenticated attacker to exhaust the receiver thread’s JVM stack...

SUSE CVE-2026-59927

Mistune is a Python Markdown parser with renderers and plugins. Prior to 3.3.0, the Include directive in src/mistune/directives/include.py detects only direct self-includes and not indirect cycles, allowing two markdown files that include each other to trigger unbounded recursion, raise...

p11-kit: Stack exhaustion via unbounded recursion in RPC attribute parsing

A flaw was found in p11-kit. The RPC message attribute parsing functions p11rpcmessagegetattribute and p11rpcmessagegetattributearrayvalue form a mutually-recursive call chain with no recursion depth limit when processing nested CKAWRAPTEMPLATE, CKAUNWRAPTEMPLATE, and CKADERIVETEMPLATE attributes...
