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-2023-53842 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-2023-53842/ (Markdown: https://insights.sbomify.com/CVE-2023-53842/index.md)","id":"CVE-2023-53842","markdown":"https://insights.sbomify.com/CVE-2023-53842/index.md","name":"CVE-2023-53842","record":{"aliases":["BELL-CVE-2023-53842","DEBIAN-CVE-2023-53842","GHSA-65w4-2cj7-2f5c","UBUNTU-CVE-2023-53842"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel audio driver","requires_auth":"none","summary":"A resource leak in the Linux kernel WCD-MBHC codec driver causes audio card initialization failures, leading to 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\nASoC: codecs: wcd-mbhc-v2: fix resource leaks on component remove\n\nThe MBHC resources must be released on component probe failure and\nremoval so can not be tied to the lifetime of the component device.\n\nThis is specifically needed to allow probe deferrals of the sound card\nwhich otherwise fails when reprobing the codec component:\n\n    snd-sc8280xp sound: ASoC: failed to instantiate card -517\n    genirq: Flags mismatch irq 299. 00002001 (mbhc sw intr) vs. 00002001 (mbhc sw intr)\n    wcd938x_codec audio-codec: Failed to request mbhc interrupts -16\n    wcd938x_codec audio-codec: mbhc initialization failed\n    wcd938x_codec audio-codec: ASoC: error at snd_soc_component_probe on audio-codec: -16\n    snd-sc8280xp sound: ASoC: failed to instantiate card -16","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":"ASoC: codecs: wcd-mbhc-v2: fix resource leaks on component remove","id":"CVE-2023-53842","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":4,"next":{"headline":"net: openvswitch: reject negative ifindex","id":"CVE-2023-53843"},"packages":[],"prev":{"headline":"devlink: report devlink_port_type_warn source device","id":"CVE-2023-53841"},"products":["Linux"],"published":"2025-12-09","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":"A resource leak in the Linux kernel WCD-MBHC codec driver causes audio card initialization failures, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2023-53842/"}
