{"id":"CVE-2026-93283","summary":"i3c: master: Fix device_register() error path","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ni3c: master: Fix device_register() error path\n\nWhen device_register() fails in i3c_master_register_new_i3c_devs(),\nput_device() is called to drop the reference taken by\ndevice_register().  That drops the last reference, so the device's\nrelease callback i3c_device_release() runs and frees the i3c_device.\n\nTwo problems follow from that:\n\ni3c_device_release() does WARN_ON(i3cdev-\u003edesc), so it warns because\ndesc-\u003edev-\u003edesc still points back at the descriptor.  Clear it before\ncalling put_device().\n\nAfter put_device() frees the i3c_device, desc-\u003edev is left pointing at\nfreed memory, so clear desc-\u003edev as well.  That prevents, for example,\ni3c_master_unregister_i3c_devs() seeing desc-\u003edev as non-NULL and\ndereferencing it.","modified":"2026-11-13T04:02:49.859745882Z","published":"2026-09-24T15:52:26.252Z","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/2026/93xxx/CVE-2026-93283.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/20a2b6df91fd782ef2ff551febef594d0b46a9a7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5bf498623f8397d45f85f14cd631c5e5a565c2fb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6ecf17bf5fe8da51a6e3fc9e03a76898fcc5c6cf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/74be657d98a8d684c0475f3cbd450ef2a30ffc73"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7ef12e1dd06e442eebf370f6e53c41bd056d0f22"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7f8e2c4f3704d9774bb26b49b1ad6a60ae57d4a0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a14dbdf471001dd0601b0c491184990c178a199c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d22ad96f1a0c89e0ba66a2facc7430f0923919e3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93283.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93283"},{"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":"1832ed55df45f4145335ad992fb83813cdc58b5d"},{"fixed":"5bf498623f8397d45f85f14cd631c5e5a565c2fb"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"d48fe8d98171e0fffdeaa8b37ce0a6444bff819b"},{"fixed":"20a2b6df91fd782ef2ff551febef594d0b46a9a7"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"174ae0a3b89e7804e4ea3d31bd83d6e43f39568c"},{"fixed":"a14dbdf471001dd0601b0c491184990c178a199c"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e49a51a96b531f1b4bcd8d358e645b6c74ef67e6"},{"fixed":"d22ad96f1a0c89e0ba66a2facc7430f0923919e3"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"cab63f64887616e3c4e31cfd8103320be6ebc8d3"},{"fixed":"7f8e2c4f3704d9774bb26b49b1ad6a60ae57d4a0"},{"fixed":"7ef12e1dd06e442eebf370f6e53c41bd056d0f22"},{"fixed":"6ecf17bf5fe8da51a6e3fc9e03a76898fcc5c6cf"},{"fixed":"74be657d98a8d684c0475f3cbd450ef2a30ffc73"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"204beeb509d37669de34560e83bb8abffe7ee63a"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"b24cf43d9babf1265a2bb0ae8d198267cef43b83"}]}],"versions":["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","v5.10.257","v5.10.256","v5.10.255","v5.10.254","v5.10.253","v5.10.252","v5.10.251","v5.10.250","v5.10.249","v5.10.248","v5.10.247","v5.10.246","v5.10.245","v5.10.244","v5.10.243","v5.10.242","v5.10.241","v5.10.240","v5.10.239","v5.10.238","v5.10.237","v5.10.236","v5.10.235","v5.10.234","v5.10.233","v5.10.232","v5.10.231","v5.10.230","v5.10.229","v5.10.228","v5.10.227","v5.10.226","v5.10.225","v5.10.224","v5.10.223","v5.10.222","v5.10.221","v5.10.220","v5.10.219","v5.10.218","v5.10.217","v5.10.216","v5.10.215","v5.10.214","v5.10.213","v5.10.212","v5.10.211","v5.10.210","v5.10.209","v5.10.208","v5.10.207","v5.10.206","v5.10.205","v5.10.204","v5.10.203","v5.10.202","v5.10.201","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","v5.15.208","v5.15.207","v5.15.206","v5.15.205","v5.15.204","v5.15.203","v5.15.202","v5.15.201","v5.15.200","v5.15.199","v5.15.198","v5.15.197","v5.15.196","v5.15.195","v5.15.194","v5.15.193","v5.15.192","v5.15.191","v5.15.190","v5.15.189","v5.15.188","v5.15.187","v5.15.186","v5.15.185","v5.15.184","v5.15.183","v5.15.182","v5.15.181","v5.15.180","v5.15.179","v5.15.178","v5.15.177","v5.15.176","v5.15.175","v5.15.174","v5.15.173","v5.15.172","v5.15.171","v5.15.170","v5.15.169","v5.15.168","v5.15.167","v5.15.166","v5.15.165","v5.15.164","v5.15.163","v5.15.162","v5.15.161","v5.15.160","v5.15.159","v5.15.158","v5.15.157","v5.15.156","v5.15.155","v5.15.154","v5.15.153","v5.15.152","v5.15.151","v5.15.150","v5.15.149","v5.15.148","v5.15.147","v5.15.146","v5.15.145","v5.15.144","v5.15.143","v5.15.142","v5.15.141","v5.15.140","v5.15.139","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.
