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-2026-90308 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-2026-90308/ (Markdown: https://insights.sbomify.com/CVE-2026-90308/index.md)","id":"CVE-2026-90308","markdown":"https://insights.sbomify.com/CVE-2026-90308/index.md","name":"CVE-2026-90308","record":{"aliases":["AZL-102026","BELL-CVE-2026-90308","DEBIAN-CVE-2026-90308","GHSA-rmmh-jvpf-4wxx","UBUNTU-CVE-2026-90308"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel RDMA driver","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel's erdma driver allows use-after-free of Queue Pair resources, potentially leading to code execution or system crashes.","user_interaction":"not_required","vuln_class":"use_after_free"},"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/erdma: Hold QP references for AE and CM processing\n\nAE QP fatal events and iWARP CM paths load QPs from dev-\u003eqp_xa\nand then use or reference them outside the xarray lock.\nerdma_destroy_qp() can drop the destroy-path reference and free QP\nresources while such a lookup is in flight.\n\nAdd erdma_qp_get_by_qpn() to acquire a kref under the xarray\nlock with kref_get_unless_zero().
