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-2026-53216 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2026-53216/ (Markdown: https://insights.sbomify.com/CVE-2026-53216/index.md)","id":"CVE-2026-53216","markdown":"https://insights.sbomify.com/CVE-2026-53216/index.md","name":"CVE-2026-53216","record":{"aliases":["BELL-CVE-2026-53216","DEBIAN-CVE-2026-53216","GHSA-8vc2-h54q-6258","ROOT-OS-DEBIAN-11-CVE-2026-53216","ROOT-OS-DEBIAN-12-CVE-2026-53216","ROOT-OS-UBUNTU-2204-CVE-2026-53216","ROOT-OS-UBUNTU-2404-CVE-2026-53216","UBUNTU-CVE-2026-53216"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel network driver","requires_auth":"none","summary":"A flaw in the Linux kernel mvpp2 driver allows memory corruption via XDP tail adjustment, potentially leading to code execution or denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: mvpp2: limit XDP frame size to the RX buffer\n\nmvpp2 has short and long BM pools, and short pool buffers can be smaller\nthan PAGE_SIZE.
