An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-11828 in the wild and no public exploit code.\n\nAffected product: Oppo Color OS. 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-2020-11828/ (Markdown: https://insights.sbomify.com/CVE-2020-11828/index.md)","id":"CVE-2020-11828","markdown":"https://insights.sbomify.com/CVE-2020-11828/index.md","name":"CVE-2020-11828","record":{"aliases":["GHSA-6mcg-qcwq-jvvg"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"ColorOS mobile OS","requires_auth":"none","summary":"Uninitialized stack memory in ColorOS SurfaceFlinger allows attackers to leak data and bypass ASLR protections.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OPPO","cpe":[{"product":"coloros","vendor":"oppo"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-908","name":"Use of Uninitialized Resource"}],"description":"In ColorOS (oppo mobile phone operating system, based on AOSP frameworks/native code position/services/surfaceflinger surfaceflinger.CPP), RGB is defined on the stack but uninitialized, so when the screenShot function to RGB value assignment, will not initialize the value is returned to the attackers, leading to values on the stack information leakage, the vulnerability can be used to bypass attackers ALSR.","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":"Information disclosure in Color OS","id":"CVE-2020-11828","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in com.coloros.codebook","id":"CVE-2020-11829"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2020-11827"},"products":["Color OS"],"published":"2020-04-21","related":[{"cvss_score":9.8,"headline":"Privilege escalation in com.coloros.codebook","id":"CVE-2020-11829","kev_date_added":null,"published":"2020-11-19"},{"cvss_score":7.8,"headline":"Privilege escalation in OPPO Android Phone","id":"CVE-2021-23244","kev_date_added":null,"published":"2021-12-27"},{"cvss_score":7.5,"headline":"Information disclosure in ACE2","id":"CVE-2021-23246","kev_date_added":null,"published":"2022-03-11"},{"cvss_score":7.4,"headline":"Command Injection In OPPO Service","id":"CVE-2023-26310","kev_date_added":null,"published":"2023-08-09"}],"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":["Oppo"]},"summary":"Uninitialized stack memory in ColorOS SurfaceFlinger allows attackers to leak data and bypass ASLR protections.","url":"https://insights.sbomify.com/CVE-2020-11828/"}
