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-2026-89531 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-2026-89531/ (Markdown: https://insights.sbomify.com/CVE-2026-89531/index.md)","id":"CVE-2026-89531","markdown":"https://insights.sbomify.com/CVE-2026-89531/index.md","name":"CVE-2026-89531","record":{"aliases":["AZL-100640","BELL-CVE-2026-89531","DEBIAN-CVE-2026-89531","GHSA-vgrv-wfr9-vqh2","UBUNTU-CVE-2026-89531"],"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 remote attacker can cause a denial of service by triggering memory allocation failures in the Linux kernel's svcrdma module, leading to resource leaks.","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 connection when transport allocation fails\n\nhandle_connect_req() returns without action when\nsvc_rdma_create_xprt() fails to allocate the new transport.\nThe CM core returns 0 for CONNECT_REQUEST events, so it does\nnot destroy the new rdma_cm_id.
