A bug was found in containerd prior to versions 1.6.38, 1.7.27, and 2.0.4 where containers launched with a User set as a `UID:GID` larger than the maximum 32-bit signed integer can cause an overflow condition where the container ultimately runs as root (UID 0). This could cause unexpected behavior for environments that require containers to run as a non-root user. This bug has been fixed in containerd 1.6.38, 1.7.27, and 2.04. As a workaround, ensure that only trusted images are used and that only trusted users have permissions to import images.","publishedAt":"2025-03-17T21:32:37.894Z","updatedAt":"2025-05-04T22:02:39.748Z","severity":{"score":4.6,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["containerd containerd"],"affected":[{"vendor":"containerd","product":"containerd","versions":[{"version":"< 1.6.38","status":"affected"},{"version":">= 1.7.0-beta.0, < 1.7.27","status":"affected"},{"version":">= 2.0.0-beta.0, < 2.0.4","status":"affected"}]}],"references":["https://github.com/containerd/containerd/security/advisories/GHSA-265r-hfxg-fhmg","https://github.com/containerd/containerd/commit/05044ec0a9a75232cad458027ca83437aae3f4da","https://github.com/containerd/containerd/commit/1a43cb6a1035441f9aca8f5666a9b3ef9e70ab20","https://github.com/containerd/containerd/commit/cf158e884cfe4812a6c371b59e4ea9bc4c46e51a","https://lists.debian.org/debian-lts-announce/2025/05/msg00005.html"],"weaknesses":["CWE-190"],"ingestedAt":"2026-10-29T20:07:39.287Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2024/40xxx/CVE-2024-40635.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2024-40635","state":"PUBLISHED","datePublished":"2025-03-17T21:32:37.894Z","dateUpdated":"2025-05-04T22:02:39.748Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2024-07-08T16:13:15.511Z"},"containers":{"cna":{"title":"containerd has an integer overflow in User ID handling","descriptions":[{"lang":"en","value":"containerd is an open-source container runtime.
