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-2022-48827 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-2022-48827/ (Markdown: https://insights.sbomify.com/CVE-2022-48827/index.md)","id":"CVE-2022-48827","markdown":"https://insights.sbomify.com/CVE-2022-48827/index.md","name":"CVE-2022-48827","record":{"aliases":["DEBIAN-CVE-2022-48827","GHSA-g43c-r7c6-fhrv","UBUNTU-CVE-2022-48827"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel NFS","requires_auth":"none","summary":"An integer overflow in the Linux kernel NFS server causes a denial of service when reading near the maximum file offset, leading to infinite client retries.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"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":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nNFSD: Fix the behavior of READ near OFFSET_MAX\n\nDan Aloni reports:\n\u003e Due to commit 8cfb9015280d (\"NFS: Always provide aligned buffers to\n\u003e the RPC read layers\") on the client, a read of 0xfff is aligned up\n\u003e to server rsize of 0x1000.\n\u003e\n\u003e As a result, in a test where the server has a file of size\n\u003e 0x7fffffffffffffff, and the client tries to read from the offset\n\u003e 0x7ffffffffffff000, the read causes loff_t overflow in the server\n\u003e and it returns an NFS code of EINVAL to the client.
