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-2020-11834 in the wild and no public exploit code.\n\nAffected product: OPPO Find X2. 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-2020-11834/ (Markdown: https://insights.sbomify.com/CVE-2020-11834/index.md)","id":"CVE-2020-11834","markdown":"https://insights.sbomify.com/CVE-2020-11834/index.md","name":"CVE-2020-11834","record":{"aliases":["GHSA-9vr7-48xw-7c8q"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OPPO Android OS","requires_auth":"low_privilege","summary":"A missing length check in the OPPO charger driver allows attackers to trigger memory corruption, potentially leading to code execution or privilege escalation on Find X2 devices.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OPPO","cpe":[{"product":"find_x2_pro_firmware","vendor":"oppo"},{"product":"reno3_pro_firmware","vendor":"oppo"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"In /SM8250_Q_Master/android/vendor/oppo_charger/oppo/oppo_vooc.c, the function proc_fastchg_fw_update_write in proc_fastchg_fw_update_write does not check the parameter len, resulting in a vulnerability.","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":"Memory corruption in OPPO Find X2","id":"CVE-2020-11834","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in OPPO Find X2","id":"CVE-2020-11835"},"packages":[],"prev":{"headline":"Memory corruption in OPPO Find X2","id":"CVE-2020-11833"},"products":["OPPO Find X2"],"published":"2020-12-31","related":[{"cvss_score":5.5,"headline":"Memory corruption in OPPO Find X2","id":"CVE-2020-11832","kev_date_added":null,"published":"2020-12-31"},{"cvss_score":5.5,"headline":"Memory corruption in OPPO Find X2","id":"CVE-2020-11833","kev_date_added":null,"published":"2020-12-31"},{"cvss_score":5.5,"headline":"Memory corruption in OPPO Find X2","id":"CVE-2020-11835","kev_date_added":null,"published":"2020-12-31"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"A missing length check in the OPPO charger driver allows attackers to trigger memory corruption, potentially leading to code execution or privilege escalation on Find X2 devices.","url":"https://insights.sbomify.com/CVE-2020-11834/"}
