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-2022-36765 and fix it if it is affected.\n\nWhat it is: CVE-2022-36765 is a high-severity vulnerability in TianoCore edk2, published on 9 Jan 2024. 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-2022-36765 in the wild and no public exploit code.\n\nAffected product: TianoCore edk2. 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-2022-36765/ (Markdown: https://insights.sbomify.com/CVE-2022-36765/index.md)","id":"CVE-2022-36765","markdown":"https://insights.sbomify.com/CVE-2022-36765/index.md","name":"CVE-2022-36765","record":{"aliases":["AZL-38920","AZL-39424","AZL-39556","BELL-CVE-2022-36765","DEBIAN-CVE-2022-36765","GHSA-ch4w-v7m3-g8wx","OESA-2024-1350","SUSE-SU-2026:0120-1","SUSE-SU-2026:0121-1","SUSE-SU-2026:0212-1","SUSE-SU-2026:0213-1","SUSE-SU-2026:20246-1","UBUNTU-CVE-2022-36765"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"UEFI firmware","requires_auth":"low_privilege","summary":"An integer overflow in EDK2's CreateHob function allows local attackers to trigger a buffer overflow, potentially compromising system confidentiality, integrity, and availability.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TianoCore","cpe":[{"product":"edk2","vendor":"tianocore"}],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"},{"id":"CWE-680","name":"Integer Overflow to Buffer Overflow"}],"description":"EDK2 is susceptible to a vulnerability in the CreateHob() function, allowing a user to trigger a integer overflow to buffer overflow via a local network.
