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-2025-40108 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-2025-40108/ (Markdown: https://insights.sbomify.com/CVE-2025-40108/index.md)","id":"CVE-2025-40108","markdown":"https://insights.sbomify.com/CVE-2025-40108/index.md","name":"CVE-2025-40108","record":{"aliases":["BELL-CVE-2025-40108","GHSA-wqc8-4945-8xxr","UBUNTU-CVE-2025-40108"],"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":"none","summary":"A regression in the Qualcomm GENI serial driver causes system hangs during boot, resulting in a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\nserial: qcom-geni: Fix blocked task\n\nRevert commit 1afa70632c39 (\"serial: qcom-geni: Enable PM runtime for\nserial driver\") and its dependent commit 86fa39dd6fb7 (\"serial:\nqcom-geni: Enable Serial on SA8255p Qualcomm platforms\") because the\nfirst one causes regression - hang task on Qualcomm RB1 board (QRB2210)\nand unable to use serial at all during normal boot:\n\n  INFO: task kworker/u16:0:12 blocked for more than 42 seconds.\n        Not tainted 6.17.0-rc1-00004-g53e760d89498 #9\n  \"echo 0 \u003e /proc/sys/kernel/hung_task_timeout_secs\" disables this message.\n  task:kworker/u16:0   state:D stack:0     pid:12    tgid:12    ppid:2      task_flags:0x4208060 flags:0x00000010\n  Workqueue: async async_run_entry_fn\n  Call trace:\n   __switch_to+0xe8/0x1a0 (T)\n   __schedule+0x290/0x7c0\n   schedule+0x34/0x118\n   rpm_resume+0x14c/0x66c\n   rpm_resume+0x2a4/0x66c\n   rpm_resume+0x2a4/0x66c\n   rpm_resume+0x2a4/0x66c\n   __pm_runtime_resume+0x50/0x9c\n   __driver_probe_device+0x58/0x120\n   driver_probe_device+0x3c/0x154\n   __driver_attach_async_helper+0x4c/0xc0\n   async_run_entry_fn+0x34/0xe0\n   process_one_work+0x148/0x290\n   worker_thread+0x2c4/0x3e0\n   kthread+0x118/0x1c0\n   ret_from_fork+0x10/0x20\n\nThe issue was reported on 12th of August and was ignored by author of\ncommits introducing issue for two weeks.
