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-2026-92513 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-2026-92513/ (Markdown: https://insights.sbomify.com/CVE-2026-92513/index.md)","id":"CVE-2026-92513","markdown":"https://insights.sbomify.com/CVE-2026-92513/index.md","name":"CVE-2026-92513","record":{"aliases":["BELL-CVE-2026-92513","DEBIAN-CVE-2026-92513","GHSA-r87w-wp8m-2wvh","UBUNTU-CVE-2026-92513"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel RDMA driver","requires_auth":"none","summary":"A race condition in the Linux kernel mana_ib driver allows a use-after-free, potentially enabling local attackers to execute code or escalate privileges.","user_interaction":"not_required","vuln_class":"use_after_free"},"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\nRDMA/mana_ib: drain QP references after partial table insertion\n\nmana_table_store_ud_qp() publishes a QP at its send-queue id before\ninserting the receive-queue id, dropping the XArray lock between the two\nxa_insert_irq() calls.
