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-2026-90194 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-2026-90194/ (Markdown: https://insights.sbomify.com/CVE-2026-90194/index.md)","id":"CVE-2026-90194","markdown":"https://insights.sbomify.com/CVE-2026-90194/index.md","name":"CVE-2026-90194","record":{"aliases":["AZL-102036","BELL-CVE-2026-90194","DEBIAN-CVE-2026-90194","GHSA-37ww-vf7x-2832","UBUNTU-CVE-2026-90194"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A memory leak in the Linux kernel ACPI scan module can lead to resource exhaustion and denial of service when device addition fails.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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\nACPI: scan: fix bus ID cleanup on device_add() failures\n\nWhen device_add() fails after acpi_device_set_name() has allocated an\ninstance ID and a new acpi_device_bus_id has been linked into\nacpi_bus_id_list, the rollback path only removes wakeup_list and\ndetaches the ACPI handle data.\n\nThat leaves the bus-ID bookkeeping behind and keeps the allocated\ninstance number consumed.\n\nMove the bus-ID cleanup and wakeup-list removal into a single helper.\n\nUse it from both the normal device teardown path and the device_add()\nrollback path.
