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-2022-50865 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-2022-50865/ (Markdown: https://insights.sbomify.com/CVE-2022-50865/index.md)","id":"CVE-2022-50865","markdown":"https://insights.sbomify.com/CVE-2022-50865/index.md","name":"CVE-2022-50865","record":{"aliases":["DEBIAN-CVE-2022-50865","GHSA-2qmc-x97c-8pmc","UBUNTU-CVE-2022-50865"],"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":"A signed integer overflow in the Linux kernel TCP backlog handling can lead to a denial of service condition.","user_interaction":"not_required","vuln_class":"integer_overflow"},"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\ntcp: fix a signed-integer-overflow bug in tcp_add_backlog()\n\nThe type of sk_rcvbuf and sk_sndbuf in struct sock is int, and\nin tcp_add_backlog(), the variable limit is caculated by adding\nsk_rcvbuf, sk_sndbuf and 64 * 1024, it may exceed the max value\nof int and overflow.
