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-2026-31550 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2026-31550/ (Markdown: https://insights.sbomify.com/CVE-2026-31550/index.md)","id":"CVE-2026-31550","markdown":"https://insights.sbomify.com/CVE-2026-31550/index.md","name":"CVE-2026-31550","record":{"aliases":["BELL-CVE-2026-31550","DEBIAN-CVE-2026-31550","GHSA-jccg-jh56-vh7j","ROOT-OS-DEBIAN-11-CVE-2026-31550","ROOT-OS-DEBIAN-12-CVE-2026-31550","ROOT-OS-UBUNTU-2204-CVE-2026-31550","ROOT-OS-UBUNTU-2404-CVE-2026-31550","UBUNTU-CVE-2026-31550"],"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":"Insufficient timeout in the BCM2835 power domain driver can cause system hangs or bus faults during runtime power management suspend operations.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\npmdomain: bcm: bcm2835-power: Increase ASB control timeout\n\nThe bcm2835_asb_control() function uses a tight polling loop to wait\nfor the ASB bridge to acknowledge a request.
