It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2022-0492 in the wild since at least 2 Jun 2026.\n\nAffected product: Canonical Ubuntu Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2022-0492/ (Markdown: https://insights.sbomify.com/CVE-2022-0492/index.md)","id":"CVE-2022-0492","markdown":"https://insights.sbomify.com/CVE-2022-0492/index.md","name":"CVE-2022-0492","record":{"aliases":["A-224859358","AZL-8966","DEBIAN-CVE-2022-0492","PUB-A-224859358","RHSA-2022:4642","RHSA-2022:4644","RHSA-2022:4655","RHSA-2022:4717","RHSA-2022:4721","SUSE-SU-2022:0991-1","SUSE-SU-2022:1036-1","UBUNTU-CVE-2022-0492"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"Attackers can escalate privileges and bypass namespace isolation by exploiting the cgroups v1 release_agent feature in the Linux kernel.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"linux_kernel","vendor":"linux"},{"product":"bootstrap_os","vendor":"netapp"},{"product":"h300s_firmware","vendor":"netapp"},{"product":"h410c_firmware","vendor":"netapp"},{"product":"h410s_firmware","vendor":"netapp"},{"product":"h500s_firmware","vendor":"netapp"},{"product":"h700s_firmware","vendor":"netapp"},{"product":"solidfire\\,_enterprise_sds_\\\u0026_hci_storage_node","vendor":"netapp"},{"product":"solidfire_\\\u0026_hci_management_node","vendor":"netapp"},{"product":"codeready_linux_builder","vendor":"redhat"},{"product":"codeready_linux_builder_for_power_little_endian","vendor":"redhat"},{"product":"enterprise_linux","vendor":"redhat"},{"product":"enterprise_linux_eus","vendor":"redhat"},{"product":"enterprise_linux_for_ibm_z_systems","vendor":"redhat"},{"product":"enterprise_linux_for_ibm_z_systems_eus","vendor":"redhat"},{"product":"enterprise_linux_for_power_little_endian","vendor":"redhat"},{"product":"enterprise_linux_for_power_little_endian_eus","vendor":"redhat"},{"product":"enterprise_linux_for_real_time_for_nfv_tus","vendor":"redhat"},{"product":"enterprise_linux_for_real_time_tus","vendor":"redhat"},{"product":"enterprise_linux_server_aus","vendor":"redhat"},{"product":"enterprise_linux_server_for_power_little_endian_update_services_for_sap_solutions","vendor":"redhat"},{"product":"enterprise_linux_server_tus","vendor":"redhat"},{"product":"enterprise_linux_server_update_services_for_sap_solutions","vendor":"redhat"},{"product":"virtualization_host","vendor":"redhat"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"},{"id":"CWE-287","name":"Improper Authentication"}],"description":"A vulnerability was found in the Linux kernel’s cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function.
