libp2p: yamux connection DoS via oversized data frame

SummaryThe 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 t...

GO-2026-6172 WITHDRAWN: Backend frame lengths cause pre-validation memory exhaustion in github.com/lib/pq

This report has been withdrawn with reason: "Report mistakenly added without having CVE / GHSA associated". github.com/lib/pq allocates the backend-declared PostgreSQL frame payload before applying a protocol length bound or a phase-specific message-type check. A malicious server or active networ...

CVE-2026-61634 RabbitMQ Java client accepts broker frames larger than the negotiated AMQP frame_max

The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.33.0, the AMQP connection tuning path records the negotiated AMQP framemax value, but src/main/java/com/rabbitmq/client/impl/SocketFrameHandler.java and...

CVE-2026-72114

A flaw was found in the Linux kernel's Controller Area Network CAN Broadcom bcm driver. This vulnerability arises from insufficient validation of frame lengths when processing Remote Transmission Request RTR replies. An attacker could exploit this by sending a specially crafted RTR reply, which m...

CVE-2026-72114

In the Linux kernel CAN BCM subsystem, CVE-2026-72114 is due to bcm_rx_setup() not validating the frame length for RTR-reply frames configured via RX_SETUP with RX_RTR_FRAME, unlike bcm_tx_setup() which validates cf->len against CAN/CAN FD DLC limits. The vulnerability is resolved by adding va...
