It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-74297 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-2026-74297/ (Markdown: https://insights.sbomify.com/CVE-2026-74297/index.md)","id":"CVE-2026-74297","markdown":"https://insights.sbomify.com/CVE-2026-74297/index.md","name":"CVE-2026-74297","record":{"aliases":["BELL-CVE-2026-74297","DEBIAN-CVE-2026-74297","GHSA-p4jx-gh49-76wv","UBUNTU-CVE-2026-74297"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel RDMA","requires_auth":"low_privilege","summary":"A local attacker can trigger undefined behavior via integer overflow in RDMA WQE size calculation, potentially causing denial of service or code execution.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/mlx5: Fix undefined shift of user RQ WQE size\n\nset_rq_size() computes the RQ WQE size as \"1 \u003c\u003c rq_wqe_shift\" based on\nthe user-provided rq_wqe_shift, which is only checked to be greater than\n32, so shifts of 32 are still accepted.
