{"id":"OESA-2026-4568","summary":"containerd security update","details":"containerd is an industry-standard container runtime with an emphasis on simplicity, robustness and portability.  It is available as a daemon for Linux and Windows, which can manage the complete container lifecycle of its host system: image transfer and storage, container execution and supervision, low-level storage and network attachments, etc.\r\n\r\nSecurity Fix(es):\n\ncontainerd is an open-source container runtime. 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.(CVE-2026-95838)","modified":"2026-10-29T09:15:29.514604406Z","published":"2026-10-29T09:03:02Z","upstream":["CVE-2026-95838"],"database_specific":{"severity":"Medium"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4568"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-95838"}],"affected":[{"package":{"name":"containerd","ecosystem":"openEuler:22.03-LTS-SP4","purl":"pkg:rpm/openEuler/containerd&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.2.0-330.oe2203sp4"}]}],"ecosystem_specific":{"src":["containerd-1.2.0-330.oe2203sp4.src.rpm"],"x86_64":["containerd-1.2.0-330.oe2203sp4.x86_64.rpm"],"aarch64":["containerd-1.2.0-330.oe2203sp4.aarch64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-4568.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"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"}]}
