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-2026-73568: Uncontrolled Resource Consumption

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-2026-72671: Missing Authorization

io.netty/netty-codec-http2: Netty: Denial of Service via HTTP/2 DATA frame memory leak

A flaw was found in Netty, a network application framework. A remote, unauthenticated attacker can exploit this vulnerability by sending specially crafted HTTP/2 DATA frames to applications that use Netty and have HTTP/2 content decompression enabled. This can lead to memory exhaustion, causing t...

GHSA-HMJ8-5XMH-5573 libp2p: yamux connection DoS via oversized data frame

Summary The yamux stream multiplexer in py-libp2p does not validate incoming DATA frame lengths against the receive window before reading the frame body. Any peer that completes a standard libp2p handshake can send a single 12-byte frame claiming a 4 GB body, causing the victim's yamux read loop ...
