CVE-2021-22883 (GCVE-0-2021-22883)
Vulnerability from cvelistv5 – Published: 2021-03-03 17:38 – Updated: 2025-04-30 22:24
VLAI?
Summary
Node.js before 10.24.0, 12.21.0, 14.16.0, and 15.10.0 is vulnerable to a denial of service attack when too many connection attempts with an 'unknownProtocol' are established. This leads to a leak of file descriptors. If a file descriptor limit is configured on the system, then the server is unable to accept new connections and prevent the process also from opening, e.g. a file. If no file descriptor limit is configured, then this lead to an excessive memory usage and cause the system to run out of memory.
Severity ?
No CVSS data available.
