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-2025-37819 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-2025-37819/ (Markdown: https://insights.sbomify.com/CVE-2025-37819/index.md)","id":"CVE-2025-37819","markdown":"https://insights.sbomify.com/CVE-2025-37819/index.md","name":"CVE-2025-37819","record":{"aliases":["BELL-CVE-2025-37819","DEBIAN-CVE-2025-37819","GHSA-5c72-frqm-r8r4","ROOT-OS-DEBIAN-11-CVE-2025-37819","ROOT-OS-DEBIAN-12-CVE-2025-37819","ROOT-OS-UBUNTU-2204-CVE-2025-37819","ROOT-OS-UBUNTU-2404-CVE-2025-37819","UBUNTU-CVE-2025-37819"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel's GICv2m driver can cause a system crash during PCI host bridge probing when ACPI is enabled.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nirqchip/gic-v2m: Prevent use after free of gicv2m_get_fwnode()\n\nWith ACPI in place, gicv2m_get_fwnode() is registered with the pci\nsubsystem as pci_msi_get_fwnode_cb(), which may get invoked at runtime\nduring a PCI host bridge probe.
