It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-16933 and fix it if it is affected.\n\nWhat it is: CVE-2026-16933 is a high-severity vulnerability in IBM Power Systems Firmware, published on 19 Aug 2026. 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-2026-16933 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-2026-16933/ (Markdown: https://insights.sbomify.com/CVE-2026-16933/index.md)","id":"CVE-2026-16933","markdown":"https://insights.sbomify.com/CVE-2026-16933/index.md","name":"CVE-2026-16933","record":{"aliases":["GHSA-vhm3-9qxc-9hqg"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IBM Power Systems Firmware","requires_auth":"high_privilege","summary":"Attackers with BMC access can exploit an integer overflow to read and write arbitrary host memory, gaining full control over the system.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"power_hardware_management_console_\\(7063-cr2\\)_firmware","vendor":"ibm"},{"product":"power_system_ac922_\\(8335-gth\\)_firmware","vendor":"ibm"},{"product":"power_system_ac922_\\(8335-gtx\\)_firmware","vendor":"ibm"},{"product":"power_system_e1050_\\(9043-mrx\\)_firmware","vendor":"ibm"},{"product":"power_system_e1080_\\(9080-hex\\)_firmware","vendor":"ibm"},{"product":"power_system_e1150_\\(9043-mru\\)_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_l1022_\\(9786-22h\\)_firmware","vendor":"ibm"},{"product":"power_system_l1024_\\(9786-42h\\)_firmware","vendor":"ibm"},{"product":"power_system_l1122_\\(9856-22h\\)_firmware","vendor":"ibm"},{"product":"power_system_l1124_\\(9856-42h\\)_firmware","vendor":"ibm"},{"product":"power_system_s1012_\\(9028-21b\\)_firmware","vendor":"ibm"},{"product":"power_system_s1014_\\(9105-41b\\)_firmware","vendor":"ibm"},{"product":"power_system_s1022_\\(9105-22a\\)_firmware","vendor":"ibm"},{"product":"power_system_s1022s_\\(9105-22b\\)_firmware","vendor":"ibm"},{"product":"power_system_s1024_\\(9105-42a\\)_firmware","vendor":"ibm"},{"product":"power_system_s1112_\\(9242-21b\\)_firmware","vendor":"ibm"},{"product":"power_system_s1112_\\(9242-21t\\)_firmware","vendor":"ibm"},{"product":"power_system_s1114_\\(9824-41b\\)_firmware","vendor":"ibm"},{"product":"power_system_s1122_\\(9824-22a\\)_firmware","vendor":"ibm"},{"product":"power_system_s1122s_\\(9824-22b\\)_firmware","vendor":"ibm"},{"product":"power_system_s1124_\\(9824-42a\\)_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":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"IBM Power Systems Firmware FW1120.00, FW1110.00 through FW1110.30, FW1060.00 through FW1060.80, FW950.00 through FW950.H2, OP940.00 through OP940.a1 (Power9), and OP940.00 through OP940.81 (Power HMC) is affected by a vulnerability in the interface between the BMC/FSP and the host system.
