For users with the following configuration: 1. An allow policy that selects a Layer 3 destination and a port range `AND` 2. A Layer 7 allow policy that selects a specific port within the first policy's range the Layer 7 enforcement would not occur for the traffic selected by the Layer 7 policy. This issue only affects users who use Cilium's port range functionality, which was introduced in Cilium v1.16. This issue is patched in PR #35150. This issue affects Cilium v1.16 between v1.16.0 and v1.16.3 inclusive. This issue is patched in Cilium v1.16.4. Users are advised to upgrade. Users with network policies that match the pattern described above can work around the issue by rewriting any policies that use port ranges to individually specify the ports permitted for traffic.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N","score":5.8},"cwes":["CWE-755"],"references":["https://github.com/cilium/cilium/pull/35150","https://github.com/cilium/cilium/security/advisories/GHSA-xg58-75qf-9r67"],"products":["cilium:cilium"],"source":"nvd","synced_at":"2026-10-19T21:57:34.731061660+00:00"},"epss":{"cve":"CVE-2024-52529","score":0.0052,"percentile":0.44213,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-xg58-75qf-9r67","url":"https://osv.dev/vulnerability/GHSA-xg58-75qf-9r67","summary":"Cilium's Layer 7 policy enforcement may not occur in policies with wildcarded port ranges","modified":"2026-09-10T03:50:21.162948314Z","packages":[{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.16.0 <1.16.4"],"fixed":["1.16.4"]}]},{"id":"GO-2024-3290","url":"https://osv.dev/vulnerability/GO-2024-3290","summary":"Cilium's Layer 7 policy enforcement may not occur in policies with wildcarded port ranges in github.com/cilium/cilium","modified":"2026-02-04T04:08:48.056063Z","packages":[{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.16.0 <1.16.4"],"fixed":["1.16.4"]}]}],"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).
