Prior to libcontainer 0.5.3, while creating a tenant container, the tenant builder accepts a list of capabilities to be added in the spec of tenant container. The logic here adds the given capabilities to all capabilities of main container if present in spec, otherwise simply set provided capabilities as capabilities of the tenant container. However, setting inherited caps in any case for tenant container can lead to elevation of capabilities, similar to CVE-2022-29162. This does not affect youki binary itself. This is only applicable if you are using libcontainer directly and using the tenant builder.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","score":5.9},"cwes":["CWE-276"],"references":["https://github.com/opencontainers/runc/security/advisories/GHSA-f3fp-gc8g-vw66","https://github.com/youki-dev/youki/blob/9e63fa4da1672a78ca45100f3059a732784a5174/crates/libcontainer/src/container/tenant_builder.rs#L408","https://github.com/youki-dev/youki/commit/747e342d2026fbf3a395db3e2a491ebef00082f1","https://github.com/youki-dev/youki/security/advisories/GHSA-5w4j-f78p-4wh9"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:00:28.034033815+00:00"},"epss":{"cve":"CVE-2025-27612","score":0.00178,"percentile":0.0735,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-5w4j-f78p-4wh9","url":"https://osv.dev/vulnerability/GHSA-5w4j-f78p-4wh9","summary":"Libcontainer is affected by capabilities elevation similar to GHSA-f3fp-gc8g-vw66","modified":"2026-02-04T03:55:59.577515Z","packages":[{"ecosystem":"crates.io","name":"libcontainer","purl":"pkg:cargo/libcontainer","ranges":["<0.5.3"],"fixed":["0.5.3"]}]}],"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).
