CVE-2024-48077: Emqx Nanomq

High severity, CVSS 7.5. EPSS: 0.3% chance of exploitation in the next 30 days.

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.
