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-2026-53355 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-2026-53355/ (Markdown: https://insights.sbomify.com/CVE-2026-53355/index.md)","id":"CVE-2026-53355","markdown":"https://insights.sbomify.com/CVE-2026-53355/index.md","name":"CVE-2026-53355","record":{"aliases":["BELL-CVE-2026-53355","DEBIAN-CVE-2026-53355","GHSA-3hv8-6fp5-2gcr","ROOT-OS-DEBIAN-11-CVE-2026-53355","ROOT-OS-DEBIAN-12-CVE-2026-53355","ROOT-OS-UBUNTU-2204-CVE-2026-53355","ROOT-OS-UBUNTU-2404-CVE-2026-53355","UBUNTU-CVE-2026-53355"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel RDS","requires_auth":"none","summary":"A null pointer dereference in the Linux kernel RDS module can cause a denial of service during connection setup failures.","user_interaction":"not_required","vuln_class":"null_dereference"},"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":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: rds: clear i_sends on setup unwind\n\nThe RDS IB connection teardown path is written so it can run during\npartial startup and on repeated shutdown attempts.
