In versions prior to 0.45.1 an attacker node can cause a victim node to allocate a large number of small memory chunks, which can ultimately lead to the victim’s process running out of memory and thus getting killed by its operating system. When executed continuously, this can lead to a denial of service attack, especially relevant on a larger scale when run against more than one node of a libp2p based network. Users are advised to upgrade to `libp2p` `v0.45.1` or above. Users unable to upgrade should reference the DoS Mitigation page for more information on how to incorporate mitigation strategies, monitor their application, and respond to attacks: https://docs.libp2p.io/reference/dos-mitigation/.","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","CWE-400"],"references":["https://github.com/libp2p/rust-libp2p/security/advisories/GHSA-jvgw-gccv-q5p8","https://github.com/libp2p/rust-libp2p/security/advisories/GHSA-jvgw-gccv-q5p8"],"products":["protocol:libp2p"],"source":"nvd","synced_at":"2026-10-19T21:37:28.463369388+00:00"},"epss":{"cve":"CVE-2022-23486","score":0.00734,"percentile":0.5443,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-jvgw-gccv-q5p8","url":"https://osv.dev/vulnerability/GHSA-jvgw-gccv-q5p8","summary":"libp2p DoS vulnerability from lack of resource management","modified":"2023-11-08T04:08:18.938960Z","packages":[{"ecosystem":"crates.io","name":"libp2p","purl":"pkg:cargo/libp2p","ranges":["<0.45.1"],"fixed":["0.45.1"]}]},{"id":"RUSTSEC-2022-0084","url":"https://osv.dev/vulnerability/RUSTSEC-2022-0084","summary":"libp2p Lack of resource management DoS","modified":"2026-10-12T18:00:04.410061721Z","packages":[{"ecosystem":"crates.io","name":"libp2p","purl":"pkg:cargo/libp2p","ranges":[">=0.0.0-0 <0.45.1"],"fixed":["0.45.1"]}]}],"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).
