CVE-2026-73568

py-libp2p is the Python implementation of the libp2p networking stack. In 0.7.0 and earlier, the yamux handleincoming method in libp2p/streammuxer/yamux/yamux.py reads an attacker-controlled 32-bit DATA frame length with readexactly before validating it against MAXWINDOWSIZE or checking whether...

CVE-2026-73568

py-libp2p (Python implementation of libp2p) before 0.7.0 has a yamux handle_incoming() flaw in libp2p/stream_muxer/yamux/yamux.py: it reads a 32-bit DATA frame length with read_exactly() before validating against MAX_WINDOW_SIZE or checking stream_id. A peer completing the Noise handshake can sen...

CVE-2025-29606

The CVE-2025-29606 entry impacts the Python libp2p project (py-libp2p) prior to 0.2.3, where a peer can trigger a DoS by sending a very large RSA key. Root cause: insufficient validation of RSA key sizes, leading to resource exhaustion on the target. Affected component/file is the RSA key handlin...
