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-2025-40352 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-2025-40352/ (Markdown: https://insights.sbomify.com/CVE-2025-40352/index.md)","id":"CVE-2025-40352","markdown":"https://insights.sbomify.com/CVE-2025-40352/index.md","name":"CVE-2025-40352","record":{"aliases":["BELL-CVE-2025-40352","DEBIAN-CVE-2025-40352","GHSA-5r3f-3vjw-2jp6","UBUNTU-CVE-2025-40352"],"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":"none","summary":"Missing sysfs attribute initialization in the Mellanox BlueField-3 PMC driver triggers a kernel warning and potential instability during boot.","user_interaction":"not_required","vuln_class":"other"},"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\nplatform/mellanox: mlxbf-pmc: add sysfs_attr_init() to count_clock init\n\nThe lock-related debug logic (CONFIG_LOCK_STAT) in the kernel is noting\nthe following warning when the BlueField-3 SOC is booted:\n\n  BUG: key ffff00008a3402a8 has not been registered!\n  ------------[ cut here ]------------\n  DEBUG_LOCKS_WARN_ON(1)\n  WARNING: CPU: 4 PID: 592 at kernel/locking/lockdep.c:4801 lockdep_init_map_type+0x1d4/0x2a0\n\u003csnip\u003e\n  Call trace:\n   lockdep_init_map_type+0x1d4/0x2a0\n   __kernfs_create_file+0x84/0x140\n   sysfs_add_file_mode_ns+0xcc/0x1cc\n   internal_create_group+0x110/0x3d4\n   internal_create_groups.part.0+0x54/0xcc\n   sysfs_create_groups+0x24/0x40\n   device_add+0x6e8/0x93c\n   device_register+0x28/0x40\n   __hwmon_device_register+0x4b0/0x8a0\n   devm_hwmon_device_register_with_groups+0x7c/0xe0\n   mlxbf_pmc_probe+0x1e8/0x3e0 [mlxbf_pmc]\n   platform_probe+0x70/0x110\n\nThe mlxbf_pmc driver must call sysfs_attr_init() during the\ninitialization of the \"count_clock\" data structure to avoid\nthis warning.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"platform/mellanox: mlxbf-pmc: add sysfs_attr_init() to count_clock init","id":"CVE-2025-40352","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"arm64: mte: Do not warn if the page is already tagged in copy_highpage()","id":"CVE-2025-40353"},"packages":[],"prev":{"headline":"hfsplus: fix KMSAN uninit-value issue in hfsplus_delete_cat()","id":"CVE-2025-40351"},"products":["Linux"],"published":"2025-12-16","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"Missing sysfs attribute initialization in the Mellanox BlueField-3 PMC driver triggers a kernel warning and potential instability during boot.","url":"https://insights.sbomify.com/CVE-2025-40352/"}
