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-2023-54306 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-2023-54306/ (Markdown: https://insights.sbomify.com/CVE-2023-54306/index.md)","id":"CVE-2023-54306","markdown":"https://insights.sbomify.com/CVE-2023-54306/index.md","name":"CVE-2023-54306","record":{"aliases":["BELL-CVE-2023-54306","DEBIAN-CVE-2023-54306","GHSA-f7xx-6pgx-v4hg","UBUNTU-CVE-2023-54306"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"An adversarial receiver can cause Linux kernel tasks to hang indefinitely by keeping the receive window at zero, leading to a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: tls: avoid hanging tasks on the tx_lock\n\nsyzbot sent a hung task report and Eric explains that adversarial\nreceiver may keep RWIN at 0 for a long time, so we are not guaranteed\nto make forward progress.
