{"cve":"CVE-2024-22189","nvd":{"published":"2024-04-04T15:15:37.990","modified":"2026-06-17T07:10:54.083","status":"Deferred","description":"quic-go is an implementation of the QUIC protocol in Go. Prior to version 0.42.0, an attacker can cause its peer to run out of memory sending a large number of `NEW_CONNECTION_ID` frames that retire old connection IDs. The receiver is supposed to respond to each retirement frame with a `RETIRE_CONNECTION_ID` frame. The attacker can prevent the receiver from sending out (the vast majority of) these `RETIRE_CONNECTION_ID` frames by collapsing the peers congestion window (by selectively acknowledging received packets) and by manipulating the peer's RTT estimate. Version 0.42.0 contains a patch for the issue. No known workarounds are available.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-770"],"references":["https://github.com/quic-go/quic-go/commit/4a99b816ae3ab03ae5449d15aac45147c85ed47a","https://github.com/quic-go/quic-go/security/advisories/GHSA-c33x-xqrf-c478","https://seemann.io/posts/2024-03-19-exploiting-quics-connection-id-management","https://www.youtube.com/watch?v=JqXtYcZAtIA&t=3683s","https://github.com/quic-go/quic-go/commit/4a99b816ae3ab03ae5449d15aac45147c85ed47a"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:48:32.179249784+00:00"},"epss":{"cve":"CVE-2024-22189","score":0.01109,"percentile":0.65912,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-c33x-xqrf-c478","url":"https://osv.dev/vulnerability/GHSA-c33x-xqrf-c478","summary":"QUIC's Connection ID Mechanism vulnerable to Memory Exhaustion Attack","modified":"2026-09-10T03:50:11.209249573Z","packages":[{"ecosystem":"Go","name":"github.com/quic-go/quic-go","purl":"pkg:golang/github.com/quic-go/quic-go","ranges":["<0.42.0"],"fixed":["0.42.0"]}]},{"id":"GO-2024-2682","url":"https://osv.dev/vulnerability/GO-2024-2682","summary":"Denial of service via connection starvation in github.com/quic-go/quic-go","modified":"2026-02-04T02:49:59.898307Z","packages":[{"ecosystem":"Go","name":"github.com/quic-go/quic-go","purl":"pkg:golang/github.com/quic-go/quic-go","ranges":["<0.42.0"],"fixed":["0.42.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
