{"id":"CVE-2025-68205","summary":"ALSA: hda/hdmi: Fix breakage at probing nvhdmi-mcp driver","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: hda/hdmi: Fix breakage at probing nvhdmi-mcp driver\n\nAfter restructuring and splitting the HDMI codec driver code, each\nHDMI codec driver contains the own build_controls and build_pcms ops.\nA copy-n-paste error put the wrong entries for nvhdmi-mcp driver; both\nbuild_controls and build_pcms are swapped.  Unfortunately both\ncallbacks have the very same form, and the compiler didn't complain\nit, either.  This resulted in a NULL dereference because the PCM\ninstance hasn't been initialized at calling the build_controls\ncallback.\n\nFix it by passing the proper entries.","modified":"2026-03-20T12:46:17.718505Z","published":"2025-12-16T13:48:32.888Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68205.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/82420bd4e17bdaba8453fbf9e10c58c9ed0c9727"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d2aed6fac1148528181affb781aa683d6569042b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68205.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68205"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"ad781b550f9a8829e3dae4bd3d18c4a126a53d04"},{"fixed":"d2aed6fac1148528181affb781aa683d6569042b"},{"fixed":"82420bd4e17bdaba8453fbf9e10c58c9ed0c9727"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-68205.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.17.0"},{"fixed":"6.17.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-68205.json"}}],"schema_version":"1.7.5"}
