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-2026-80912 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2026-80912/ (Markdown: https://insights.sbomify.com/CVE-2026-80912/index.md)","id":"CVE-2026-80912","markdown":"https://insights.sbomify.com/CVE-2026-80912/index.md","name":"CVE-2026-80912","record":{"aliases":["AZL-99443","BELL-CVE-2026-80912","DEBIAN-CVE-2026-80912","GHSA-5v22-vqg5-vrr8","UBUNTU-CVE-2026-80912"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A null pointer dereference in the Linux kernel SELinux subsystem allows local attackers to cause a denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nselinux: reject an unclaimed class value in security_get_classes()\n\nsecurity_get_classes() sizes an array by p_classes.nprim and fills it at\nvalue - 1, so a class value the policy never defines leaves a NULL.\nsel_make_classes() passes every entry to sel_make_dir(), reaching the same\nd_alloc_name() dereference as the permission array.
