FKIE_CVE-2024-48077

Vulnerability from fkie_nvd - Published: 2026-01-15 20:16 - Updated: 2026-04-03 16:16
Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
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.
