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-2025-40097 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-2025-40097/ (Markdown: https://insights.sbomify.com/CVE-2025-40097/index.md)","id":"CVE-2025-40097","markdown":"https://insights.sbomify.com/CVE-2025-40097/index.md","name":"CVE-2025-40097","record":{"aliases":["BELL-CVE-2025-40097","DEBIAN-CVE-2025-40097","GHSA-9cqx-9fcv-mjx8","ROOT-OS-DEBIAN-12-CVE-2025-40097","ROOT-OS-DEBIAN-13-CVE-2025-40097","ROOT-OS-UBUNTU-2204-CVE-2025-40097","ROOT-OS-UBUNTU-2404-CVE-2025-40097","UBUNTU-CVE-2025-40097"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A missing pointer check in the Linux kernel ALSA HDA driver can cause a null pointer dereference, leading to a system crash.","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: Fix missing pointer check in hda_component_manager_init function\n\nThe __component_match_add function may assign the 'matchptr' pointer\nthe value ERR_PTR(-ENOMEM), which will subsequently be dereferenced.\n\nThe call stack leading to the error looks like this:\n\nhda_component_manager_init\n|-\u003e component_match_add\n    |-\u003e component_match_add_release\n        |-\u003e __component_match_add ( ... ,**matchptr, ... )\n            |-\u003e *matchptr = ERR_PTR(-ENOMEM);       // assign\n|-\u003e component_master_add_with_match( ...  match)\n    |-\u003e component_match_realloc(match, match-\u003enum); // dereference\n\nAdd IS_ERR() check to prevent the crash.\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: Fix missing pointer check in hda_component_manager_init function","id":"CVE-2025-40097","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2025"},"n_packages":0,"n_references":5,"next":{"headline":"ALSA: hda: cs35l41: Fix NULL pointer dereference in cs35l41_get_acpi_mute_state()","id":"CVE-2025-40098"},"packages":[],"prev":{"headline":"drm/sched: Fix potential double free in drm_sched_job_add_resv_dependencies","id":"CVE-2025-40096"},"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":"2026-10-03","vendors":["Linux"]},"summary":"A missing pointer check in the Linux kernel ALSA HDA driver can cause a null pointer dereference, leading to a system crash.","url":"https://insights.sbomify.com/CVE-2025-40097/"}
