{"id":"CVE-2026-98066","summary":"ALSA: caiaq: Fix potential double-free at error path","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: caiaq: Fix potential double-free at error path\n\nThe fix for caiaq driver's resource management to handle the errors\ntries to release the resources in a common destructor call, but as a\nsashiko review for another patch suggested, some of the audio\nresources such as URBs have been already freed, and this may lead to a\ndouble-free.\n\nFor addressing the double-free, call the common destructor function\nfrom each place, and assure that the resource pointers get cleared.","modified":"2026-11-13T04:07:25.011432453Z","published":"2026-09-25T10:24:08.999Z","related":["SUSE-SU-2026:24550-1","SUSE-SU-2026:24619-1","SUSE-SU-2026:24643-1","SUSE-SU-2026:24648-1","SUSE-SU-2026:24651-1","SUSE-SU-2026:24662-1","SUSE-SU-2026:5091-1","openSUSE-SU-2026:12074-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98066.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1dd715ca0568e4833ed5878f49b028b449941096"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2883d65a3d9a8d9a682cdb003e6ab7fb28bb17f8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3b26ceef88c110f4d188387cffa0df78657be904"},{"type":"WEB","url":"https://git.kernel.org/stable/c/75b20534d7a37e091db585f8b505a3b77b7e81a8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b629ae7b3eddc6812d5af3614b8c1bd76d65fa75"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b6cd6f1664a0bc8038b9baa7e6f5fe8e4142d056"},{"type":"WEB","url":"https://git.kernel.org/stable/c/da93fd9002d980bb02b729c5d5aeefeb252dd110"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ddfff1cec52b7deec6c770ba85de4dab6221d0a2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98066.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98066"},{"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":"da938aa9fc7826901921dcea225948ab21a97e45"},{"fixed":"ddfff1cec52b7deec6c770ba85de4dab6221d0a2"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"09616e25f502080ba684fc7fcf959d1376ab756d"},{"fixed":"da93fd9002d980bb02b729c5d5aeefeb252dd110"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"b956e48371f2ff72b76be9a829800ecec963bd45"},{"fixed":"b6cd6f1664a0bc8038b9baa7e6f5fe8e4142d056"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"f537e3ad69609f6924a4db6b4a7f6561f5288bdd"},{"fixed":"75b20534d7a37e091db585f8b505a3b77b7e81a8"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6251e3e256337a30160ef59ab1580dde4d1acd28"},{"fixed":"2883d65a3d9a8d9a682cdb003e6ab7fb28bb17f8"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e59ecd4ee3a450db6cb4e4ecaa3efdd593f80056"},{"fixed":"1dd715ca0568e4833ed5878f49b028b449941096"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"28abd224db4a49560b452115bca3672a20e45b2f"},{"fixed":"b629ae7b3eddc6812d5af3614b8c1bd76d65fa75"},{"fixed":"3b26ceef88c110f4d188387cffa0df78657be904"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"096dd8519cf2f768e9e14f224b627f7aaee1a9c5"}]}],"versions":["v5.10.270","v5.10.269","v5.10.268","v5.10.267","v5.10.266","v5.10.265","v5.10.264","v5.10.263","v5.10.262","v5.10.261","v5.10.260","v5.10.259","v5.10.258","v5.15.221","v5.15.220","v5.15.219","v5.15.218","v5.15.217","v5.15.216","v5.15.215","v5.15.214","v5.15.213","v5.15.212","v5.15.211","v5.15.210","v5.15.209","v6.1.188","v6.1.187","v6.1.186","v6.1.185","v6.1.184","v6.1.183","v6.1.182","v6.1.181","v6.1.180","v6.1.179","v6.1.178","v6.1.177","v6.1.176","v6.1.175","v6.6.157","v6.6.156","v6.6.155","v6.6.154","v6.6.153","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","v6.12.110","v6.12.109","v6.12.108","v6.12.107","v6.12.106","v6.12.105","v6.12.104","v6.12.103","v6.12.102","v6.12.101","v6.12.100","v6.12.99","v6.12.98","v6.12.97","v6.12.96","v6.12.95","v6.12.94","v6.12.93","v6.12.92","v6.12.91","v6.12.90","v6.12.89","v6.12.88","v6.12.87","v6.12.86","v6.18.52","v6.18.51","v6.18.50","v6.18.49","v6.18.48","v6.18.47","v6.18.46","v6.18.45","v6.18.44","v6.18.43","v6.18.42","v6.18.41","v6.18.40","v6.18.39","v6.18.38","v6.18.37","v6.18.36","v6.18.35","v6.18.34","v6.18.33","v6.18.32","v6.18.31","v6.18.30","v6.18.29","v6.18.28","v6.18.27","v7.0.14","v7.0.13","v7.0.12","v7.0.11","v7.0.10","v7.0.9","v7.0.8","v7.0.7","v7.0.6","v7.0.5","v7.0.4"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98066.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.10.258"},{"fixed":"5.10.271"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.15.209"},{"fixed":"5.15.222"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.1.175"},{"fixed":"6.1.189"}]},{"type
