Who is impacted?_\nAll versions of CRI-O running on cgroupv2 nodes. \nUnchecked access to an experimental annotation allows a container to be unconfined. Back in 2021, [support was added](https://github.com/cri-o/cri-o/pull/4479) to support an experimental annotation that allows a user to request special resources in cgroupv2. It was supposed to be gated by an experimental annotation: `io.kubernetes.cri-o.UnifiedCgroup`, which was supposed to be filtered from the [list of allowed annotations](https://github.com/cri-o/cri-o/blob/main/pkg/config/workloads.go#L103-L107) . However, there is a bug in this code which allows any user to specify this annotation, regardless of whether it's enabled on the node. The consequences of this are a pod can specify any amount of memory/cpu and get it, circumventing the kubernetes scheduler, and potentially be able to DOS a node. \n### Patches\n_Has the problem been patched? What versions should users upgrade to?_\n1.29.1, 1.28.3, 1.27.3\n\n### Workarounds\n_Is there a way for users to fix or remediate the vulnerability without upgrading?_\nuse cgroupv1\n\n### References\n_Are there any links users can visit to find out more?_","references":[{"reference_url":"https://access.redhat.com/errata/RHSA-2024:0195","reference_id":"","reference_type":"","scores":[{"value":"6.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2024-01-10T15:24:28Z/"}],"url":"https://access.redhat.com/errata/RHSA-2024:0195"},{"reference_url":"https://access.redhat.com/errata/RHSA-2024:0207","reference_id":"","reference_type":"","scores":[{"value":"6.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2024-01-10T15:24:28Z/"}],"url":"https://access.redhat.com/errata/RHSA-2024:0207"},{"reference_url":"https://access.redhat.com/hydra/rest/securitydata/cve/CVE-2023-6476.json","reference_id":"","reference_type":"","scores":[{"value":"6.5","scoring_system":"cvssv3","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}],"url":"https://access.redhat.com/hydra/rest/securitydata/cve/CVE-2023-6476.json"},{"reference_url":"https://access.redhat.com/security/cve/CVE-2023-6476","reference_id":"","reference_type":"","scores":[{"value":"6.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2024-01-10T15:24:28Z/"}],"url":"https://access.redhat.com/security/cve/CVE-2023-6476"},{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2023-6476","reference_id":"","reference_type":"","scores":[{"value":"0.00299","scoring_system":"epss","scoring_elements":"0.53574","published_at":"2026-06-08T12:55:00Z"},{"value":"0.00299","scoring_system":"epss","scoring_elements":"0.53598","published_at":"2026-06-09T12:55:00Z"},{"value":"0.00299","scoring_system":"epss","scoring_elements":"0.53602","published_at":"2026-06-05T12:55:00Z"},{"value":"0.00299","scoring_system":"epss","scoring_elements":"0.53611","published_at":"2026-06-06T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2023-6476"},{"reference_url":"https://bugzilla.redhat.com/show_bug.cgi?id=2253994","reference_id":"","reference_type":"","scores":[{"value":"6.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2024-01-10T15:24:28Z/"}],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2253994"},{"reference_url":"https://github.com/cri-o/cri-o","reference_id":"","reference_type":"","scores":[{"value":"6.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/cri-o/cri-o"},{"reference_url":"https://github.com/cri-o/cri-o/blob/main/pkg/config/workloads.go#L103-L107","reference_id":"","reference_type":"","scores":[{"value":"6.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/cri-o/cri-o/blob/main/pkg/config/workloads.go#L103-L107"},{"reference_url":"https://github.com/cri-o/cri-o/commit/75effcb1a25851a736e82dba1f7d8cee93ee159e","reference_id":"","reference_type":"","scores":[{"value":"6.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/cri-o/cri-o/commit/75effcb1a25851a736e82dba1f7d8cee93ee159e"},{"reference_url":"https://github.com/cri-o/cri-o/pull/4479","reference_id":"","reference_type":"","scores":[{"value":"6.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/cri-o/cri-o/pull/4479"},{"reference_url":"https://github.com/cri-o/cri-o/security/advisories/GHSA-p4rx-7wvg-fwrc","reference_id":"","reference_type":"","scores":[{"value":"6.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/cri-o/cri-o/security/advisories/GHSA-p4rx-7wvg-fwrc"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2023-6476","reference_id":"","reference_type":"","scores":[{"value":"6.5","scoring_system":"cvssv3.1","s
