{"id":"CVE-2026-31399","summary":"nvdimm/bus: Fix potential use after free in asynchronous initialization","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnvdimm/bus: Fix potential use after free in asynchronous initialization\n\nDingisoul with KASAN reports a use after free if device_add() fails in\nnd_async_device_register().\n\nCommit b6eae0f61db2 (\"libnvdimm: Hold reference on parent while\nscheduling async init\") correctly added a reference on the parent device\nto be held until asynchronous initialization was complete.  However, if\ndevice_add() results in an allocation failure the ref count of the\ndevice drops to 0 prior to the parent pointer being accessed.  Thus\nresulting in use after free.\n\nThe bug bot AI correctly identified the fix.  Save a reference to the\nparent pointer to be used to drop the parent reference regardless of the\noutcome of device_add().","modified":"2026-11-07T02:30:53.340605043Z","published":"2026-04-03T15:16:03.246Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31399.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2c638259ad750833fd46a0cf57672a618542d84c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6fc36c2a925ceaba203eb13d75a8f0879a2c121b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/84af19855d1abdee3c9d57c0684e2868e391793c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9a0fb16ba5b372465a3a1ecd761c6fa911a4ab4d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a226e5b49e5fe8c98b14f8507de670189d191348"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a36cf138500e56f50db9f9a33222df6969b38326"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a8aec14230322ed8f1e8042b6d656c1631d41163"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e48bf8f1d2b12c1c5ba1f609edbd4cde5dadc20e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31399.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31399"},{"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":"b6eae0f61db27748606cc00dafcfd1e2c032f0a5"},{"fixed":"6fc36c2a925ceaba203eb13d75a8f0879a2c121b"},{"fixed":"a36cf138500e56f50db9f9a33222df6969b38326"},{"fixed":"9a0fb16ba5b372465a3a1ecd761c6fa911a4ab4d"},{"fixed":"e48bf8f1d2b12c1c5ba1f609edbd4cde5dadc20e"},{"fixed":"2c638259ad750833fd46a0cf57672a618542d84c"},{"fixed":"a226e5b49e5fe8c98b14f8507de670189d191348"},{"fixed":"84af19855d1abdee3c9d57c0684e2868e391793c"},{"fixed":"a8aec14230322ed8f1e8042b6d656c1631d41163"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4.4.164"},{"fixed":"4.5"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4.9.137"},{"fixed":"4.10"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4.14.81"},{"fixed":"4.15"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4.18.19"},{"fixed":"4.19"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4.19.2"},{"fixed":"4.20"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"8954771abdea5c34280870e35592c7226a816d95"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"3e63a7f25cc85d3d3e174b9b0e3489ebb7eaf4ab"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"1490de2bb0836fc0631c04d0559fdf81545b672f"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e31a8418c8df7e6771414f99ed3d95ba8aca4e05"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4f1a55a4f990016406147cf3e0c9487bf83e50f0"}]}],"versions":["v4.4.302","v4.4.301","v4.4.300","v4.4.299","v4.4.298","v4.4.297","v4.4.296","v4.4.295","v4.4.294","v4.4.293","v4.4.292","v4.4.291","v4.4.290","v4.4.289","v4.4.288","v4.4.287","v4.4.286","v4.4.285","v4.4.284","v4.4.283","v4.4.282","v4.4.281","v4.4.280","v4.4.279","v4.4.278","v4.4.277","v4.4.276","v4.4.275","v4.4.274","v4.4.273","v4.4.272","v4.4.271","v4.4.270","v4.4.269","v4.4.268","v4.4.267","v4.4.266","v4.4.265","v4.4.264","v4.4.263","v4.4.262","v4.4.261","v4.4.260","v4.4.259","v4.4.258","v4.4.257","v4.4.256","v4.4.255","v4.4.254","v4.4.253","v4.4.252","v4.4.251","v4.4.250","v4.4.249","v4.4.248","v4.4.247","v4.4.246","v4.4.245","v4.4.244","v4.4.243","v4.4.242","v4.4.241","v4.4.240","v4.4.239","v4.4.238","v4.4.237","v4.4.236","v4.4.235","v4.4.234","v4.4.233","v4.4.232","v4.4.231","v4.4.230","v4.4.229","v4.4.228","v4.4.227","v4.4.226","v4.4.225","v4.4.224","v4.4.223","v4.4.222","v4.4.221","v4.4.220","v4.4.219","v4.4.218","v4.4.217","v4.4.216","v4.4.215","v4.4.214","v4.4.213","v4.4.212","v4.4.211","v4.4.210","v4.4.209","v4.4.208","v4.4.207","v4.4.206","v4.4.205","v4.4.204","v4.4.203","v4.4.202","v4.4.201","v4.4.200","v4.4.199","v4.4.198","v4.4.197","v4.4.196","v4.4.195","v4.4.194","v4.4.193","v4.4.192","v4.4.191","v4.4.190","v4.4.189","v4.4.188","v4.4.187","v4.4.186","v4.4.185","v4.4.184","v4.4.183","v4.4.182","v4.4.181","v4.4.180","v4.4.179","v4.4.178","v4.4.177","v4.4.176","v4.4.175","v4.4.174","v4.4.173","v4.4.172","v4.4.171","v4.4.170","v4.4.169","v4.4.168","v4.4.167","v4.4.166","v4.4.165","v4.4.164","v4.9.337","v4.9.336","v4.9.335","v4.9
