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":"2026-10-12T20:17:10.577+00:00","modifiedAt":"2026-10-16T16:00:33.533+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":4.6,"severity":"MEDIUM"}],"references":["https://github.com/containerd/containerd/commit/e6ca378dcfa610d06589a3ac96aa992de866e4f0","https://github.com/containerd/containerd/security/advisories/GHSA-rp3h-jf77-q9p4"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-95838","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-400","CWE-407"],"productCriteria":[],"sourceDates":{"published":"2026-10-12T20:17:10.577","lastModified":"2026-10-16T16:00:33.533"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
