It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2021-1048 in the wild since at least 23 May 2022.\n\nAffected product: Google Android. 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-2021-1048/ (Markdown: https://insights.sbomify.com/CVE-2021-1048/index.md)","id":"CVE-2021-1048","markdown":"https://insights.sbomify.com/CVE-2021-1048/index.md","name":"CVE-2021-1048","record":{"aliases":["A-204573007","ASB-A-204573007","DEBIAN-CVE-2021-1048","GHSA-r535-rfwp-fm57","UBUNTU-CVE-2021-1048"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Android kernel","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Android kernel allows local attackers to escalate privileges without user interaction.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"google_android","cpe":[{"product":"android","vendor":"google"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In ep_loop_check_proc of eventpoll.c, there is a possible way to corrupt memory due to a use after free.
