{"id":"CVE-2026-93136","summary":"bus: mhi: ep: Fix device refcount leak in the error path of MHI device creation","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbus: mhi: ep: Fix device refcount leak in the error path of MHI device creation\n\nmhi_ep_create_device() takes one device reference for the UL channel and\nanother for the DL channel after allocating the transfer device. These\nreferences are normally released by mhi_ep_destroy_device() before the\ndevice itself is removed.\n\nIf dev_set_name() or device_add() fails, the error path currently drops\nonly one reference. The remaining channel references keep the device\nfrom being released and leave the channels associated with a device that\nwas never registered.\n\nRoute both failures through a common unwind path that drops the DL\nchannel reference, the UL channel reference, and the initial reference\nfrom device_initialize().","modified":"2026-09-18T03:48:44.567889691Z","published":"2026-09-17T16:11:37.459Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93136.json"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4fae8fd4adc7f4765463ddeb1a5fad23936432f6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/51ddb831a36102fd0ea25f354935e49abce9f0a1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5587e7871ce994bb079f97fe7e430d99627e5292"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6f12862600bb70e599a614d706a095ea5f8f9858"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8acc3813ab5015af73eeb74c9032443162f122d1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8f3f64faee335eb678fd7dca7b95dfe3d0b271fd"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93136.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93136"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"297c77a0f27312b9a04696018c4cbd47926ca92b"},{"fixed":"8acc3813ab5015af73eeb74c9032443162f122d1"},{"fixed":"51ddb831a36102fd0ea25f354935e49abce9f0a1"},{"fixed":"4fae8fd4adc7f4765463ddeb1a5fad23936432f6"},{"fixed":"5587e7871ce994bb079f97fe7e430d99627e5292"},{"fixed":"8f3f64faee335eb678fd7dca7b95dfe3d0b271fd"},{"fixed":"6f12862600bb70e599a614d706a095ea5f8f9858"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93136.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.19.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93136.json"}}],"schema_version":"1.9.0"}
