Prior to 1.7.35, 2.0.12, 2.2.8, and 2.3.5, containerd's layer unpack handler repeatedly traverses directories for certain opaque whiteout configurations. A malicious image layer can trigger repeated directory traversals while opaque whiteouts are processed. Pulling or importing the image can consume CPU, delay container startup, and reduce image-pull concurrency for unrelated deployments. This issue is fixed in versions 1.7.35, 2.0.12, 2.2.8, and 2.3.5.","state":0,"publishedAt":"2026-10-12T19:53:24.599+00:00","modifiedAt":"2026-10-13T20:24:33.956+00:00","affected":[{"ecosystem":"Vendor product","name":"containerd","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"containerd\",\n                    \"product\": \"containerd\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.7.35\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.0.0-beta.0, < 2.0.12\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.2.0, < 2.2.8\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.3.0, < 2.3.5\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","score":4.6,"severity":"MEDIUM"}],"references":["https://github.com/containerd/containerd/security/advisories/GHSA-rp3h-jf77-q9p4","https://github.com/containerd/containerd/commit/e6ca378dcfa610d06589a3ac96aa992de866e4f0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-95838","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-95838","identifiers":["CVE-2026-95838"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
