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-2025-39892 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-2025-39892/ (Markdown: https://insights.sbomify.com/CVE-2025-39892/index.md)","id":"CVE-2025-39892","markdown":"https://insights.sbomify.com/CVE-2025-39892/index.md","name":"CVE-2025-39892","record":{"aliases":["BELL-CVE-2025-39892","DEBIAN-CVE-2025-39892","GHSA-6mp7-7x6g-jprp","UBUNTU-CVE-2025-39892"],"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":"low_privilege","summary":"A null pointer dereference in the Linux kernel's ASoC core can cause a system crash during device unbinding.","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":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nASoC: soc-core: care NULL dirver name on snd_soc_lookup_component_nolocked()\n\nsoc-generic-dmaengine-pcm.c uses same dev for both CPU and Platform.\nIn such case, CPU component driver might not have driver-\u003ename, then\nsnd_soc_lookup_component_nolocked() will be NULL pointer access error.\nCare NULL driver name.\n\n\tCall trace:\n\t strcmp from snd_soc_lookup_component_nolocked+0x64/0xa4\n\t snd_soc_lookup_component_nolocked from snd_soc_unregister_component_by_driver+0x2c/0x44\n\t snd_soc_unregister_component_by_driver from snd_dmaengine_pcm_unregister+0x28/0x64\n\t snd_dmaengine_pcm_unregister from devres_release_all+0x98/0xfc\n\t devres_release_all from device_unbind_cleanup+0xc/0x60\n\t device_unbind_cleanup from really_probe+0x220/0x2c8\n\t really_probe from __driver_probe_device+0x88/0x1a0\n\t __driver_probe_device from driver_probe_device+0x30/0x110\n\tdriver_probe_device from __driver_attach+0x90/0x178\n\t__driver_attach from bus_for_each_dev+0x7c/0xcc\n\tbus_for_each_dev from bus_add_driver+0xcc/0x1ec\n\tbus_add_driver from driver_register+0x80/0x11c\n\tdriver_register from do_one_initcall+0x58/0x23c\n\tdo_one_initcall from kernel_init_freeable+0x198/0x1f4\n\tkernel_init_freeable from kernel_init+0x1c/0x12c\n\tkernel_init from ret_from_fork+0x14/0x28","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: soc-core: care NULL dirver name on snd_soc_lookup_component_nolocked()","id":"CVE-2025-39892","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"null_dereference","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"spi: spi-qpic-snand: unregister ECC engine on probe error and device remove","id":"CVE-2025-39893"},"packages":[],"prev":{"headline":"wifi: mwifiex: Initialize the chan_stats array to zero","id":"CVE-2025-39891"},"products":["Linux"],"published":"2025-10-01","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A null pointer dereference in the Linux kernel's ASoC core can cause a system crash during device unbinding.","url":"https://insights.sbomify.com/CVE-2025-39892/"}
