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-2026-43260 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-2026-43260/ (Markdown: https://insights.sbomify.com/CVE-2026-43260/index.md)","id":"CVE-2026-43260","markdown":"https://insights.sbomify.com/CVE-2026-43260/index.md","name":"CVE-2026-43260","record":{"aliases":["BELL-CVE-2026-43260","DEBIAN-CVE-2026-43260","GHSA-w6jm-j85g-vpgj","UBUNTU-CVE-2026-43260"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A logic error in the bnxt_en driver causes VNIC leaks and potential RSS context loss, leading to denial of service for network interfaces.","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":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-415","name":"Double Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nbnxt_en: Fix RSS context delete logic\n\nWe need to free the corresponding RSS context VNIC\nin FW everytime an RSS context is deleted in driver.\nCommit 667ac333dbb7 added a check to delete the VNIC\nin FW only when netif_running() is true to help delete\nRSS contexts with interface down.\n\nHaving that condition will make the driver leak VNICs\nin FW whenever close() happens with active RSS contexts.\nOn the subsequent open(), as part of RSS context restoration,\nwe will end up trying to create extra VNICs for which we\ndid not make any reservation.
