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-2026-89529 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-2026-89529/ (Markdown: https://insights.sbomify.com/CVE-2026-89529/index.md)","id":"CVE-2026-89529","markdown":"https://insights.sbomify.com/CVE-2026-89529/index.md","name":"CVE-2026-89529","record":{"aliases":["DEBIAN-CVE-2026-89529","GHSA-4fgg-mw2q-x784","UBUNTU-CVE-2026-89529"],"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 attacker can cause a resource leak and potential denial of service in the Linux kernel by sending oversized RPC/RDMA Read segments.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nsvcrdma: Reject oversized Read segments at decode time\n\nThe RPC/RDMA Read list decoder stores wire-supplied segment\nlengths without validation. xdr_count_read_segments() checks\n4-byte alignment for non-zero position values but does not\ncap the segment length.\n\nAn oversized rs_length reaches svc_rdma_build_read_segment(),\nwhich derives nr_bvec from it and can drive a large dynamic\nbvec allocation before verifying that enough rq_pages remain.\nIf the post-allocation page-overrun guard fires, the freshly\nacquired rw context is not returned, leaking the resource.\n\nReject any segment whose length exceeds the receive context's\npage budget during Read list decoding, consistent with how\nxdr_check_write_chunk() bounds Write segment counts against\nrc_maxpages.
