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-2025-40098 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-2025-40098/ (Markdown: https://insights.sbomify.com/CVE-2025-40098/index.md)","id":"CVE-2025-40098","markdown":"https://insights.sbomify.com/CVE-2025-40098/index.md","name":"CVE-2025-40098","record":{"aliases":["BELL-CVE-2025-40098","DEBIAN-CVE-2025-40098","GHSA-gjqw-7pjf-8pfr","ROOT-OS-DEBIAN-13-CVE-2025-40098","ROOT-OS-UBUNTU-2404-CVE-2025-40098","UBUNTU-CVE-2025-40098"],"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 NULL pointer dereference in the Linux kernel's CS35L41 audio driver can cause a system crash, requiring a kernel patch to prevent denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"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\nALSA: hda: cs35l41: Fix NULL pointer dereference in cs35l41_get_acpi_mute_state()\n\nReturn value of a function acpi_evaluate_dsm() is dereferenced  without\nchecking for NULL, but it is usually checked for this function.\n\nacpi_evaluate_dsm() may return NULL, when acpi_evaluate_object() returns\nacpi_status other than ACPI_SUCCESS, so add a check to prevent the crach.\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE.","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":"ALSA: hda: cs35l41: Fix NULL pointer dereference in cs35l41_get_acpi_mute_state()","id":"CVE-2025-40098","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"cifs: parse_dfs_referrals: prevent oob on malformed input","id":"CVE-2025-40099"},"packages":[],"prev":{"headline":"ALSA: hda: Fix missing pointer check in hda_component_manager_init function","id":"CVE-2025-40097"},"products":["Linux"],"published":"2025-10-30","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":"2026-08-03","vendors":["Linux"]},"summary":"A NULL pointer dereference in the Linux kernel's CS35L41 audio driver can cause a system crash, requiring a kernel patch to prevent denial of service.","url":"https://insights.sbomify.com/CVE-2025-40098/"}
