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-2025-38623 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2025-38623/ (Markdown: https://insights.sbomify.com/CVE-2025-38623/index.md)","id":"CVE-2025-38623","markdown":"https://insights.sbomify.com/CVE-2025-38623/index.md","name":"CVE-2025-38623","record":{"aliases":["AZL-66629","BELL-CVE-2025-38623","DEBIAN-CVE-2025-38623","GHSA-jm3q-7w4m-jc2w","ROOT-OS-DEBIAN-11-CVE-2025-38623","ROOT-OS-DEBIAN-12-CVE-2025-38623","ROOT-OS-DEBIAN-13-CVE-2025-38623","ROOT-OS-UBUNTU-2204-CVE-2025-38623","ROOT-OS-UBUNTU-2404-CVE-2025-38623","UBUNTU-CVE-2025-38623"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel PCI","requires_auth":"low_privilege","summary":"A flaw in the Linux kernel's PowerNV PCI hotplug driver causes system hangs and requires reboots after surprise device removals, impacting availability.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"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\nPCI: pnv_php: Fix surprise plug detection and recovery\n\nThe existing PowerNV hotplug code did not handle surprise plug events\ncorrectly, leading to a complete failure of the hotplug system after device\nremoval and a required reboot to detect new devices.\n\nThis comes down to two issues:\n\n 1) When a device is surprise removed, often the bridge upstream\n    port will cause a PE freeze on the PHB.
