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-2026-19321 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-2026-19321/ (Markdown: https://insights.sbomify.com/CVE-2026-19321/index.md)","id":"CVE-2026-19321","markdown":"https://insights.sbomify.com/CVE-2026-19321/index.md","name":"CVE-2026-19321","record":{"aliases":["GHSA-xw82-fpcp-cg6q"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IBM Power Systems Firmware","requires_auth":"high_privilege","summary":"An attacker with service access can exploit an integer overflow to leak hardware register contents, impacting confidentiality and availability.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"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_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"}],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:L/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"Power Systems Firmware FW1120.00, FW1110.00 through FW1110.30, and FW1060.00 through FW1060.80 is affected by a vulnerability in the host firmware.
