github.com/rabbitmq/amqp091-go: RabbitMQ amqp091-go: Denial of Service due to synchronous event channel blocking
A flaw was found in RabbitMQ amqp091-go, a Go AMQP 0.9.1 client. When the client synchronously sends events to application-provided channels, an unbuffered or full listener channel can cause the client's reader to block. This blockage prevents the processing of critical messages and heartbeats,...
CVE-2026-77409
RabbitMQ amqp091-go , a Go AMQP 0.9.1 client, is vulnerable to denial of service prior to 1.13.0 . The root cause is that Channel.dispatch, confirms.confirm, and Connection.dispatch0 synchronously send publisher confirmations, flow-control events, consumer cancellations, returned messages, and co...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1
Closing an event channel in the Linux kernel can lead to a deadlock. This occurs when the closure operation is performed in parallel with an unrelated Xen console action, and the handling of a Xen console interrupt occurs in a unprivileged guest. The closure of an event channel is triggered, for...
