{"id":"CVE-2026-80911","summary":"ASoC: SOF: sof-audio: Fix error path in sof_widget_setup_unlocked()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nASoC: SOF: sof-audio: Fix error path in sof_widget_setup_unlocked()\n\nIf either tplg_ops-\u003edai_config or widget_kcontrol_setup fail during widget\nsetup we would double decrement the use_count of the widget because the\nsof_widget_free_unlocked() would be called twice, similarly the core_put\nwould be invoked twice as well.\n\nSince the use_count and core_put() is handled within the widget_free\nfunction we need to return without falling through the pipe_widget_free\nlabel.\n\nThe fixes tag is picked to the last change around this part of the code\nwhich is adequately old enough for backporting purposes.","modified":"2026-09-06T03:47:08.320689489Z","published":"2026-09-04T17:19:22.045Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80911.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/8cba53b862e1437257ec206d303ff942684284f1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b270ed327380428581bbcbd85707f62e942428d7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c06995637f6a4667f2b540ac65315bfc8196a099"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d48691e70d4a9434b71039d4ed12bb0df4601acf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e780e4917d43683224812400fe3dc4816fceba75"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80911.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80911"},{"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":"3c124f09b7ff0434b076a8dec1ed446a6170b549"},{"fixed":"b270ed327380428581bbcbd85707f62e942428d7"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"31ed8da1c8e5e504710bb36863700e3389f8fc81"},{"fixed":"c06995637f6a4667f2b540ac65315bfc8196a099"},{"fixed":"8cba53b862e1437257ec206d303ff942684284f1"},{"fixed":"d48691e70d4a9434b71039d4ed12bb0df4601acf"},{"fixed":"e780e4917d43683224812400fe3dc4816fceba75"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.6.13"},{"fixed":"6.6.153"}]}],"versions":["v6.6.152","v6.6.151","v6.6.150","v6.6.149","v6.6.148","v6.6.147","v6.6.146","v6.6.145","v6.6.144","v6.6.143","v6.6.142","v6.6.141","v6.6.140","v6.6.139","v6.6.138","v6.6.137","v6.6.136","v6.6.135","v6.6.134","v6.6.133","v6.6.132","v6.6.131","v6.6.130","v6.6.129","v6.6.128","v6.6.127","v6.6.126","v6.6.125","v6.6.124","v6.6.123","v6.6.122","v6.6.121","v6.6.120","v6.6.119","v6.6.118","v6.6.117","v6.6.116","v6.6.115","v6.6.114","v6.6.113","v6.6.112","v6.6.111","v6.6.110","v6.6.109","v6.6.108","v6.6.107","v6.6.106","v6.6.105","v6.6.104","v6.6.103","v6.6.102","v6.6.101","v6.6.100","v6.6.99","v6.6.98","v6.6.97","v6.6.96","v6.6.95","v6.6.94","v6.6.93","v6.6.92","v6.6.91","v6.6.90","v6.6.89","v6.6.88","v6.6.87","v6.6.86","v6.6.85","v6.6.84","v6.6.83","v6.6.82","v6.6.81","v6.6.80","v6.6.79","v6.6.78","v6.6.77","v6.6.76","v6.6.75","v6.6.74","v6.6.73","v6.6.72","v6.6.71","v6.6.70","v6.6.69","v6.6.68","v6.6.67","v6.6.66","v6.6.65","v6.6.64","v6.6.63","v6.6.62","v6.6.61","v6.6.60","v6.6.59","v6.6.58","v6.6.57","v6.6.56","v6.6.55","v6.6.54","v6.6.53","v6.6.52","v6.6.51","v6.6.50","v6.6.49","v6.6.48","v6.6.47","v6.6.46","v6.6.45","v6.6.44","v6.6.43","v6.6.42","v6.6.41","v6.6.40","v6.6.39","v6.6.38","v6.6.37","v6.6.36","v6.6.35","v6.6.34","v6.6.33","v6.6.32","v6.6.31","v6.6.30","v6.6.29","v6.6.28","v6.6.27","v6.6.26","v6.6.25","v6.6.24","v6.6.23","v6.6.22","v6.6.21","v6.6.20","v6.6.19","v6.6.18","v6.6.17","v6.6.16","v6.6.15","v6.6.14","v6.6.13"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80911.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.153"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.105"},{"fixed":"6.18.46"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"7.1.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80911.json"}}],"schema_version":"1.9.0"}
