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-2023-53666 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-2023-53666/ (Markdown: https://insights.sbomify.com/CVE-2023-53666/index.md)","id":"CVE-2023-53666","markdown":"https://insights.sbomify.com/CVE-2023-53666/index.md","name":"CVE-2023-53666","record":{"aliases":["BELL-CVE-2023-53666","DEBIAN-CVE-2023-53666","GHSA-75gq-3wgg-m886","UBUNTU-CVE-2023-53666"],"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":"low_privilege","summary":"A missing error check in the Linux kernel WCD938x codec driver allows a local attacker to trigger a null pointer dereference, causing a system crash.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nASoC: codecs: wcd938x: fix missing mbhc init error handling\n\nMBHC initialisation can fail so add the missing error handling to avoid\ndereferencing an error pointer when later configuring the jack:\n\n    Unable to handle kernel paging request at virtual address fffffffffffffff8\n\n    pc : wcd_mbhc_start+0x28/0x380 [snd_soc_wcd_mbhc]\n    lr : wcd938x_codec_set_jack+0x28/0x48 [snd_soc_wcd938x]\n\n    Call trace:\n     wcd_mbhc_start+0x28/0x380 [snd_soc_wcd_mbhc]\n     wcd938x_codec_set_jack+0x28/0x48 [snd_soc_wcd938x]\n     snd_soc_component_set_jack+0x28/0x8c [snd_soc_core]\n     qcom_snd_wcd_jack_setup+0x7c/0x19c [snd_soc_qcom_common]\n     sc8280xp_snd_init+0x20/0x2c [snd_soc_sc8280xp]\n     snd_soc_link_init+0x28/0x90 [snd_soc_core]\n     snd_soc_bind_card+0x628/0xbfc [snd_soc_core]\n     snd_soc_register_card+0xec/0x104 [snd_soc_core]\n     devm_snd_soc_register_card+0x4c/0xa4 [snd_soc_core]\n     sc8280xp_platform_probe+0xf0/0x108 [snd_soc_sc8280xp]","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: wcd938x: fix missing mbhc init error handling","id":"CVE-2023-53666","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"null_dereference","year":"2023"},"n_packages":0,"n_references":4,"next":{"headline":"net: cdc_ncm: Deal with too low values of dwNtbOutMaxSize","id":"CVE-2023-53667"},"packages":[],"prev":{"headline":"md: don't dereference mddev after export_rdev()","id":"CVE-2023-53665"},"products":["Linux"],"published":"2025-10-07","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A missing error check in the Linux kernel WCD938x codec driver allows a local attacker to trigger a null pointer dereference, causing a system crash.","url":"https://insights.sbomify.com/CVE-2023-53666/"}
