{"id":"GHSA-8f93-j3fx-72f3","summary":"CRI-O has Potential High Memory Consumption from File Read","details":"There's a vulnerability in the CRI-O application where when container is launched with securityContext.runAsUser specifying a non-existent user, CRI-O attempts to create the user, reading the container's entire /etc/passwd file into memory. If this file is excessively large, it can cause the a high memory consumption leading applications to be killed due to out-of-memory. As a result a denial-of-service can be achieved, possibly disrupting other pods and services running in the same host.","aliases":["CVE-2025-4437","GO-2025-3897"],"modified":"2025-08-29T20:38:22Z","published":"2025-08-20T15:31:41Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2025-08-20T19:10:29Z","nvd_published_at":"2025-08-20T13:15:28Z","cwe_ids":["CWE-770"]},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-4437"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2025-4437"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2375084"},{"type":"PACKAGE","url":"https://github.com/cri-o/cri-o"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2025-3897"}],"affected":[{"package":{"name":"github.com/cri-o/cri-o","ecosystem":"Go","purl":"pkg:golang/github.com/cri-o/cri-o"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"1.33.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/08/GHSA-8f93-j3fx-72f3/GHSA-8f93-j3fx-72f3.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H"}]}
