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-2025-37905 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-2025-37905/ (Markdown:

devices\n\nUsing device_find_child() to lookup the proper SCMI device to destroy\ncauses an unbalance in device refcount, since device_find_child() calls an\nimplicit get_device(): this, in turns, inhibits the call of the provided\nrelease methods upon devices destruction.\n\nAs a consequence, one of the structures that is not freed properly upon\ndestruction is the internal struct device_private dev-\u003ep populated by the\ndrivers subsystem core.\n\nKMemleak detects this situation since loading/unloding some SCMI driver\ncauses related devices to be created/destroyed without calling any\ndevice_release method.\n\nunreferenced object 0xffff00000f583800 (size 512):\n  comm \"insmod\", pid 227, jiffies 4294912190\n  hex dump (first 32 bytes):\n    00 00 00 00 ad 4e ad de ff
