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-2021-23887 in the wild and no public exploit code.\n\nAffected product: McAfee,LLC McAfee Data Loss Prevention (DLP) Endpoint for Windows. 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-2021-23887/ (Markdown: https://insights.sbomify.com/CVE-2021-23887/index.md)","id":"CVE-2021-23887","markdown":"https://insights.sbomify.com/CVE-2021-23887/index.md","name":"CVE-2021-23887","record":{"aliases":["GHSA-gjh7-83g9-wq47"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"McAfee DLP Endpoint","requires_auth":"low_privilege","summary":"A local low-privileged attacker can escalate privileges by manipulating memory in monitored applications via the hdlphook driver in McAfee DLP Endpoint.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"data_loss_prevention_endpoint","vendor":"mcafee"}],"cvss":{"score":7.8,"severity":"high","source":"cna","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-269","name":"Improper Privilege Management"}],"description":"Privilege Escalation vulnerability in McAfee Data Loss Prevention (DLP) Endpoint for Windows prior to 11.6.100 allows a local, low privileged, attacker to write to arbitrary controlled kernel addresses.
