Description

A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS) component. Due to an incorrect state transition, an RDS connection can bypass its expected shutdown process. This can lead to the connection becoming permanently stuck in a shutdown-queued state, potentially causing a denial of service by preventing further connection handling.
