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-2025-39818 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-2025-39818/ (Markdown: https://insights.sbomify.com/CVE-2025-39818/index.md)","id":"CVE-2025-39818","markdown":"https://insights.sbomify.com/CVE-2025-39818/index.md","name":"CVE-2025-39818","record":{"aliases":["BELL-CVE-2025-39818","DEBIAN-CVE-2025-39818","GHSA-2xm6-gr28-3f78","UBUNTU-CVE-2025-39818"],"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":"A pointer arithmetic error in the Intel THC HID driver causes out-of-bounds writes, leading to kernel crashes and denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","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-787","name":"Out-of-bounds Write"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nHID: intel-thc-hid: intel-thc: Fix incorrect pointer arithmetic in I2C regs save\n\nImproper use of secondary pointer (\u0026dev-\u003ei2c_subip_regs) caused\nkernel crash and out-of-bounds error:\n\n BUG: KASAN: slab-out-of-bounds in _regmap_bulk_read+0x449/0x510\n Write of size 4 at addr ffff888136005dc0 by task kworker/u33:5/5107\n\n CPU: 3 UID: 0 PID: 5107 Comm: kworker/u33:5 Not tainted 6.16.0+ #3 PREEMPT(voluntary)\n Workqueue: async async_run_entry_fn\n Call Trace:\n  \u003cTASK\u003e\n  dump_stack_lvl+0x76/0xa0\n  print_report+0xd1/0x660\n  ?
