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-2026-16938 in the wild and no public exploit code.\n\nAffected product: IBM Power Systems Firmware. 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-2026-16938/ (Markdown: https://insights.sbomify.com/CVE-2026-16938/index.md)","id":"CVE-2026-16938","markdown":"https://insights.sbomify.com/CVE-2026-16938/index.md","name":"CVE-2026-16938","record":{"aliases":["GHSA-v4hv-27x8-h9vq"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IBM Power Systems Firmware","requires_auth":"high_privilege","summary":"Authenticated administrators can disable system components via FSP, causing persistent denial of service requiring manual intervention.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"power_system_e1080_\\(9080-hex\\)_firmware","vendor":"ibm"},{"product":"power_system_e1180_\\(9080-heu\\)_firmware","vendor":"ibm"},{"product":"power_system_e950_\\(9040-mr9\\)_firmware","vendor":"ibm"},{"product":"power_system_e980_\\(9080-m9s\\)_firmware","vendor":"ibm"},{"product":"power_system_h922_\\(9223-22s\\)_firmware","vendor":"ibm"},{"product":"power_system_h924_\\(9223-42s\\)_firmware","vendor":"ibm"},{"product":"power_system_s914_\\(9009-41g\\)_firmware","vendor":"ibm"},{"product":"power_system_s922_\\(9009-22g\\)_firmware","vendor":"ibm"},{"product":"power_system_s924_\\(9009-42g\\)_firmware","vendor":"ibm"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"IBM Power Systems Firmware FW1120.00, FW1110.00 through FW1110.30, FW1060.00 through FW1060.80, and FW950.00 through FW950.H2 is affected by a vulnerability in access controls over privileged system configuration operations on the FSP. An attacker with authenticated administrator-level access to the FSP can place the managed system into a non-production operational mode, allowing certain system components to be disabled. This condition persists across FSP resets and requires explicit operator intervention — clearing the affected configuration — to restore normal operation. Successful exploitation results in an availability impact to the managed system.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Power System Missing Authorization","id":"CVE-2026-16938","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Custom Fields for WooCommerce \u003c 1.5.1 - Unauthenticated Arbitrary File Deletion via Path Traversal","id":"CVE-2026-16940"},"packages":[],"prev":{"headline":"Vulnerabilities in IBM AIX and PowerVM VIOS","id":"CVE-2026-16937"},"products":["Power Systems Firmware"],"published":"2026-08-19","related":[{"cvss_score":9.6,"headline":"Power System Buffer Overflow","id":"CVE-2026-16687","kev_date_added":null,"published":"2026-08-19"},{"cvss_score":9.6,"headline":"Power System Improper Certificate Validation","id":"CVE-2026-16835","kev_date_added":null,"published":"2026-08-19"},{"cvss_score":8.4,"headline":"Power System Buffer Overflow","id":"CVE-2026-16832","kev_date_added":null,"published":"2026-08-19"},{"cvss_score":8.3,"headline":"Power System Cross-Site Request Forgery (CSRF)","id":"CVE-2026-18848","kev_date_added":null,"published":"2026-08-19"},{"cvss_score":7.6,"headline":"Power System Out-of-bounds Read","id":"CVE-2026-16828","kev_date_added":null,"published":"2026-08-19"},{"cvss_score":7.1,"headline":"This Power System update is being released to address","id":"CVE-2026-93306","kev_date_added":null,"published":"2026-09-25"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-20","vendors":["IBM"]},"summary":"Authenticated administrators can disable system components via FSP, causing persistent denial of service requiring manual intervention.","url":"https://insights.sbomify.com/CVE-2026-16938/"}
