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-2025-21885 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-2025-21885/ (Markdown: https://insights.sbomify.com/CVE-2025-21885/index.md)","id":"CVE-2025-21885","markdown":"https://insights.sbomify.com/CVE-2025-21885/index.md","name":"CVE-2025-21885","record":{"aliases":["AZL-62687","AZL-69015","BELL-CVE-2025-21885","DEBIAN-CVE-2025-21885","GHSA-5h76-6cjf-jv37","ROOT-OS-DEBIAN-11-CVE-2025-21885","ROOT-OS-DEBIAN-12-CVE-2025-21885","ROOT-OS-UBUNTU-2204-CVE-2025-21885","ROOT-OS-UBUNTU-2404-CVE-2025-21885","UBUNTU-CVE-2025-21885"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A divide-by-zero error in the bnxt_re RDMA driver causes a kernel panic when creating shared receive queues for kernel consumers.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/bnxt_re: Fix the page details for the srq created by kernel consumers\n\nWhile using nvme target with use_srq on, below kernel panic is noticed.\n\n[  549.698111] bnxt_en 0000:41:00.0 enp65s0np0: FEC autoneg off encoding: Clause 91 RS(544,514)\n[  566.393619] Oops: divide error: 0000 [#1] PREEMPT SMP NOPTI\n..\n[  566.393799]  \u003cTASK\u003e\n[  566.393807]  ?
