It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-27021 in the wild and no public exploit code.\n\nAffected product: Infinera G42. 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-2025-27021/ (Markdown: https://insights.sbomify.com/CVE-2025-27021/index.md)","id":"CVE-2025-27021","markdown":"https://insights.sbomify.com/CVE-2025-27021/index.md","name":"CVE-2025-27021","record":{"aliases":["GHSA-9w8q-pjh8-6h83"],"analysis":{"component_type":"operating_system","fix_type":"configuration_change","impacts":["privilege_escalation","data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Infinera G42 OS","requires_auth":"low_privilege","summary":"Low-privileged users can escalate privileges and access kernel memory via misconfigured sudo permissions on the Infinera G42 operating system.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ENISA","cpe":[{"product":"g42_firmware","vendor":"nokia"}],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-266","name":"Incorrect Privilege Assignment"}],"description":"The misconfiguration in the sudoers configuration of the operating system in\n Infinera G42 version R6.1.3 allows low privileged OS users to \nread/write physical memory via devmem command line tool. \nThis could \nallow sensitive information disclosure, denial of service, and privilege \nescalation by tampering with kernel memory.\n\nDetails: The output of \"sudo -l\" reports the presence of \"devmem\" command \nexecutable as super user without using a password.
