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-2026-74547 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-2026-74547/ (Markdown: https://insights.sbomify.com/CVE-2026-74547/index.md)","id":"CVE-2026-74547","markdown":"https://insights.sbomify.com/CVE-2026-74547/index.md","name":"CVE-2026-74547","record":{"aliases":["AZL-96120","BELL-CVE-2026-74547","DEBIAN-CVE-2026-74547","GHSA-5cx6-pvh7-gm4r","UBUNTU-CVE-2026-74547"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A local attacker with sysfs write access can cause a CPU busy-loop and I2C bus flooding in the adt7470 hardware monitoring driver by setting specific parameters to zero.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\nhwmon: (adt7470) Fix busy-loop and I2C flooding in update thread\n\nWhen userspace configures 'auto_update_interval' to 0 via sysfs, the\nbackground kthread executes schedule_timeout_interruptible(0), which\nreturns immediately.\n\nIf 'num_temp_sensors' is concurrently or previously set to 0, the\nmsleep_interruptible() delay inside adt7470_read_temperatures() also\nbecomes 0.
