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-2020-10751 in the wild and no public exploit code.\n\nAffected product: Redhat Enterprise Linux Server. 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-2020-10751/ (Markdown: https://insights.sbomify.com/CVE-2020-10751/index.md)","id":"CVE-2020-10751","markdown":"https://insights.sbomify.com/CVE-2020-10751/index.md","name":"CVE-2020-10751","record":{"aliases":["CVE-2020-0255","DEBIAN-CVE-2020-10751","GHSA-4gwr-f7fq-56wc","UBUNTU-CVE-2020-10751"],"analysis":{"component_type":"kernel","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"Attackers can bypass SELinux security checks by sending multiple netlink messages in a single packet, allowing unauthorized access to protected resources.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"selinux","vendor":"kernel"},{"product":"enterprise_linux_server","vendor":"redhat"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"},{"id":"CWE-349","name":"Acceptance of Extraneous Untrusted Data With Trusted Data"}],"description":"A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it incorrectly assumed that an skb would only contain a single netlink message.
