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-2026-92512 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-2026-92512/ (Markdown: https://insights.sbomify.com/CVE-2026-92512/index.md)","id":"CVE-2026-92512","markdown":"https://insights.sbomify.com/CVE-2026-92512/index.md","name":"CVE-2026-92512","record":{"aliases":["AZL-102507","BELL-CVE-2026-92512","DEBIAN-CVE-2026-92512","GHSA-9c9x-p833-vgq5","UBUNTU-CVE-2026-92512"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel RDMA","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel RDMA core allows local attackers to execute arbitrary code or escalate privileges via netlink queries.","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/core: Fix use after free in ib_query_qp()\n\nWhen querying a QP via the netlink flow the only synchronization\nmechanism for the said QP is rdma_restrack_get(), meanwhile during the\nQP destroy path rdma_restrack_del() is called at the end of the\nib_destroy_qp_user() function which is too late, since by then the\nvendor specific resources for said QP would already be destroyed, and\ntill the rdma_restrack_del() is called this QP can still be accessed,\nwhich could cause the use after free below.\n\nFix this by moving the rdma_restrack_begin_del() to the start of the\nib_destroy_qp_user(), which in turn waits for all usages of the QP to be\ndone then removes it from the database to prevent access to it while it\nis being destroyed.\n\nRIP: 0010:ib_query_qp+0x15/0x50 [ib_core]\nCode: 48 83 05 5d 8e b9 ff 01 eb b5 66 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 44 00 00 48 c7 46 40 00 00 00 00 48 c7 46 78 00 00 00 00 \u003c48\u003e 8b 07 48 8b 80 88 01 00 00 48 85 c0 74 1a 48 83 05 54 91 b9 ff\nRSP: 0018:ff11000108a8f2f0 EFLAGS: 00010202\nRAX: 0000000000000000 RBX: ff11000108a8f370 RCX: ff11000108a8f370\nRDX: 0000000000000000 RSI: ff11000108a8f3d8 RDI: 0000000000000000\nRBP: ff1100010de5a000 R08: 0000000000000e80 R09: 0000000000000004\nR10: ff110001057a604c R11: 0000000000000000 R12: ff11000108a8f370\nR13: ff110001090e8000 R14: 0000000000000000 R15: ff110001057a602c\nFS:  00007f2ffd8db6c0(0000) GS:ff110008dc90b000(0000) knlGS:0000000000000000\nCS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: 0000000000000000 CR3: 000000010b9a7004 CR4: 0000000000373eb0\nCall Trace:\n \u003cTASK\u003e\n mlx5_ib_gsi_query_qp+0x21/0x50 [mlx5_ib]\n mlx5_ib_query_qp+0x689/0x9d0 [mlx5_ib]\n ib_query_qp+0x35/0x50 [ib_core]\n fill_res_qp_entry_query.isra.0+0x47/0x280 [ib_core]\n ?
