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-2026-89504 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-2026-89504/ (Markdown: https://insights.sbomify.com/CVE-2026-89504/index.md)","id":"CVE-2026-89504","markdown":"https://insights.sbomify.com/CVE-2026-89504/index.md","name":"CVE-2026-89504","record":{"aliases":["AZL-100187","BELL-CVE-2026-89504","DEBIAN-CVE-2026-89504","GHSA-w8c6-qh9v-m8g2","UBUNTU-CVE-2026-89504"],"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 regulator","requires_auth":"none","summary":"A use-after-free vulnerability in the Linux kernel's as3722 regulator driver allows attackers to cause denial of service or execute arbitrary code via a dangling pointer.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/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\nregulator: as3722_get_regulator_dt_data: fix premature of_node_put leaving dangling of_node pointer\n\nIn as3722_get_regulator_dt_data(), of_get_child_by_name() acquires a\nreference on np, which is then assigned to pdev-\u003edev.of_node.
