Description
NanoMQ v0.22.7 is vulnerable to Denial of Service (DoS) due to improper resource throttling. A crafted sequence of requests causes the recv-q queue to saturate, leading to the rapid exhaustion of system file descriptors (FDs). This exhaustion triggers a process crash, rendering the broker unable to provide services.
