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-2026-72092 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-2026-72092/ (Markdown: https://insights.sbomify.com/CVE-2026-72092/index.md)","id":"CVE-2026-72092","markdown":"https://insights.sbomify.com/CVE-2026-72092/index.md","name":"CVE-2026-72092","record":{"aliases":["BELL-CVE-2026-72092","DEBIAN-CVE-2026-72092","GHSA-phpf-xwr2-r7xq","UBUNTU-CVE-2026-72092"],"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 local attacker can crash the Linux kernel by triggering a null pointer dereference in the AMD XDNA driver via a specific ioctl on unsupported devices.","user_interaction":"not_required","vuln_class":"null_dereference"},"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\naccel/amdxdna: reject command submission on devices without a submit op\n\namdxdna_cmd_submit() calls xdna-\u003edev_info-\u003eops-\u003ecmd_submit()\nunconditionally, but only aie2_dev_ops defines that callback.\naie4_vf_ops (the AIE4 SR-IOV virtual function) does not, so a user\nAMDXDNA_EXEC_CMD ioctl on an AIE4 device reaches a NULL function-pointer\ncall and oopses the kernel.
