{"id":"CVE-2026-68181","summary":"mei: bus: access mei_device under device_lock on cleanup","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmei: bus: access mei_device under device_lock on cleanup\n\nFix couple of problems in mei_cl_bus_dev_release():\n\nmei_cl_flush_queues() is running without lock.\nbus-\u003efile_list access after mei_dev_bus_put(bus) can become a\nuse-after-free if this was the last reference to bus.\n\nProtect queues cleanup and WARN traversal by device lock there\nto avoid the concurrent access problems.\nMove WARN traversal before mei_dev_bus_put(bus).\n\nThis file uses bus variable name for mei_device, adjust\ncode of mei_cl_bus_dev_release() to use bus variable too.","modified":"2026-10-28T02:30:48.805173891Z","published":"2026-08-10T11:59:52.724Z","related":["SUSE-SU-2026:23477-1","SUSE-SU-2026:23481-1","SUSE-SU-2026:23528-1","SUSE-SU-2026:23529-1","SUSE-SU-2026:23881-1","SUSE-SU-2026:23887-1","SUSE-SU-2026:23897-1","SUSE-SU-2026:23902-1","SUSE-SU-2026:4120-1","SUSE-SU-2026:4254-1","openSUSE-SU-2026:21910-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68181.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/02e3a755086db847d795f2593ebc45e8ee4f1755"},{"type":"WEB","url":"https://git.kernel.org/stable/c/441559d4c595f839b39f0ab6a4ae628427c2fd9e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/59dd34854202d9a3faaa87a85205e553fe7150e1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7cf79e8d682fe93777268f029668ce5e214237fd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c88c030a324c9018b77894a19b2564eb66862020"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f112ea910e554d58b4b39a4492b7d302f0f4204f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68181.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68181"},{"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":"6f2a6ef86b23a30b92ad57981de537bce67bfa45"},{"fixed":"02e3a755086db847d795f2593ebc45e8ee4f1755"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"24f4ceeaeee7983c07590149556a0e33efe2ec90"},{"fixed":"441559d4c595f839b39f0ab6a4ae628427c2fd9e"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"612c8d21ce6e37b73f3106aec7ffa35959d40261"},{"fixed":"c88c030a324c9018b77894a19b2564eb66862020"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"35e8a426b16adbecae7a4e0e3c00fc8d0273db53"},{"fixed":"59dd34854202d9a3faaa87a85205e553fe7150e1"},{"fixed":"7cf79e8d682fe93777268f029668ce5e214237fd"},{"fixed":"f112ea910e554d58b4b39a4492b7d302f0f4204f"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.1.149"},{"fixed":"6.1.184"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.6.103"},{"fixed":"6.6.148"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.12.43"},{"fixed":"6.12.101"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.15.11"},{"fixed":"6.16"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.16.2"},{"fixed":"6.17"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"2f29dce5a5ae06a7db32e4491d72269329a86eeb"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"28de6ca5276a94b0589ae1bf026b89fa0eaf14c0"}]}],"versions":["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","v6.1.174","v6.1.173","v6.1.172","v6.1.171","v6.1.170","v6.1.169","v6.1.168","v6.1.167","v6.1.166","v6.1.165","v6.1.164","v6.1.163","v6.1.162","v6.1.161","v6.1.160","v6.1.159","v6.1.158","v6.1.157","v6.1.156","v6.1.155","v6.1.154","v6.1.153","v6.1.152","v6.1.151","v6.1.150","v6.1.149","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","v6.12.100","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","v6.12.85","v6.12.84","v6.12.83","v6.12.82","v6.12.81","v6.12.80","v6.12.79","v6.12.78","v6.12.77","v6.12.76","v6.12.75","v6.12.74","v6.12.73","v6.12.72","v6.12.71","v6.12.70","v6.12.69","v6.12.68","v6.12.67","v6.12.66","v6.12.65","v6.12.64","v6.12.63","v6.12.62","v6.12.61","v6.12.60","v6.12.59","v6.12.58","v6.12.57","v6.12.56","v6.12.55","v6.12.54","v6.12.53","v6.12.52","v6.12.51","v6.12.50","v6.12.49","v6.12.48","v6.12.47","v6.12.46","v6.12.45","v6.12.44","v6.12.43","v6.15.11","v6.16.12","v6.16.11","v6.16.10","v6.16.9","v6.16.8","v6.16.7","v6
