In affected versions it was found that rootless runc makes `/sys/fs/cgroup` writable in following conditons: 1. when runc is executed inside the user namespace, and the `config.json` does not specify the cgroup namespace to be unshared (e.g.., `(docker|podman|nerdctl) run --cgroupns=host`, with Rootless Docker/Podman/nerdctl) or 2. when runc is executed outside the user namespace, and `/sys` is mounted with `rbind, ro` (e.g., `runc spec --rootless`; this condition is very rare). A container may gain the write access to user-owned cgroup hierarchy `/sys/fs/cgroup/user.slice/...` on the host . Other users's cgroup hierarchies are not affected. Users are advised to upgrade to version 1.1.5. Users unable to upgrade may unshare the cgroup namespace (`(docker|podman|nerdctl) run --cgroupns=private)`. This is the default behavior of Docker/Podman/nerdctl on cgroup v2 hosts. or add `/sys/fs/cgroup` to `maskedPaths`.","title":"Vulnerability description"}],"product_status":{"fixed":["SUSE Linux Enterprise Module for Containers 12:runc-1.1.5-16.29.1.ppc64le","SUSE Linux Enterprise Module for Containers 12:runc-1.1.5-16.29.1.s390x","SUSE Linux Enterprise Module for Containers 12:runc-1.1.5-16.29.1.x86_64"]},"references":[{"category":"external","summary":"CVE-2023-25809","url":"https://www.suse.com/security/cve/CVE-2023-25809"},{"category":"external","summary":"SUSE Bug 1209884 for CVE-2023-25809","url":"https://bugzilla.suse.com/1209884"}],"remediations":[{"category":"vendor_fix","details":"To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or \"zypper patch\".\n","product_ids":["SUSE Linux Enterprise Module for Containers 12:runc-1.1.5-16.29.1.ppc64le","SUSE Linux Enterprise Module for Containers 12:runc-1.1.5-16.29.1.s390x","SUSE Linux Enterprise Module for Containers 12:runc-1.1.5-16.29.1.x86_64"]}],"scores":[{"cvss_v3":{"baseScore":2.5,"baseSeverity":"LOW","vectorString":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:N/I:N/A:L","version":"3.1"},"products":["SUSE Linux Enterprise Module for Containers 12:runc-1.1.5-16.29.1.ppc64le","SUSE Linux Enterprise Module for Containers 12:runc-1.1.5-16.29.1.s390x","SUSE Linux Enterprise Module for Containers 12:runc-1.1.5-16.29.1.x86_64"]}],"threats":[{"category":"impact","date":"2023-04-03T08:24:06Z","details":"low"}],"title":"CVE-2023-25809"},{"cve":"CVE-2023-27561","ids":[{"system_name":"SUSE CVE Page","text":"https://www.suse.com/security/cve/CVE-2023-27561"}],"notes":[{"category":"general","text":"runc through 1.1.4 has Incorrect Access Control leading to Escalation of Privileges, related to libcontainer/rootfs_linux.go.
