{"id":"OESA-2026-4237","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 versions 1.7.36, 2.0.13, 2.2.9, 2.3.6, and 2.4.1, a crafted OCI index graph can force very high CPU/memory usage during PullImage (before container start), causing long ContainerCreating stalls and, at larger sizes, node/runtime instability. Versions 1.7.36, 2.0.13, 2.2.9, 2.3.6, and 2.4.1 fix the issue.(CVE-2026-53493)","modified":"2026-10-16T12:15:04.299723304Z","published":"2026-10-16T11:58:28Z","upstream":["CVE-2026-53493"],"database_specific":{"severity":"Medium"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4237"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53493"}],"affected":[{"package":{"name":"containerd","ecosystem":"openEuler:24.03-LTS-SP3","purl":"pkg:rpm/openEuler/containerd&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.6.22-32.oe2403sp3"}]}],"ecosystem_specific":{"src":["containerd-1.6.22-32.oe2403sp3.src.rpm"],"x86_64":["containerd-1.6.22-32.oe2403sp3.x86_64.rpm"],"aarch64":["containerd-1.6.22-32.oe2403sp3.aarch64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-4237.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N"}]}
