{"id":"CVE-2026-68391","summary":"Bluetooth: mgmt: hold reference for hci_conn in mgmt_pending_cmds","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: mgmt: hold reference for hci_conn in mgmt_pending_cmds\n\nDereferencing RCU-protected pointers outside critical sections is\ninvalid and may lead to UAF.  Use of hci_conn in hci_sync callbacks also\nneeds to hold refcount to avoid UAF.\n\nTake appropriate locks for hci_conn lookups, and take refcount for\nhci_conn pointers stored in mgmt_pending_cmd so that the pointer stays\nvalid.\n\nWhen accessing conn-\u003estate, ensure hdev-\u003elock is held to avoid data\nrace.","modified":"2026-10-28T02:31:03.301435534Z","published":"2026-08-10T12:04:10.564Z","related":["ALSA-2026:70459","ALSA-2026:70498","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":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68391.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/84674dd1d3192ecb050827d3148642609c0c9dbb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b56f2ecafc08f372bf0529f9c4f3f429cb1702dc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d5b3b484b62bb0f4542e7622789d28871626cdf0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/da55f570191d5d72f10c607a7043b947eb05ea46"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ecdcb55ea1c01dda074406f38058785a69526734"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f915e74b6f18293d1d69a2a3305ef321ff7c0172"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68391.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68391"},{"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":"7b445e220db9a2c58be5d09bbbd322abf1b1452a"},{"fixed":"84674dd1d3192ecb050827d3148642609c0c9dbb"},{"fixed":"b56f2ecafc08f372bf0529f9c4f3f429cb1702dc"},{"fixed":"f915e74b6f18293d1d69a2a3305ef321ff7c0172"},{"fixed":"d5b3b484b62bb0f4542e7622789d28871626cdf0"},{"fixed":"ecdcb55ea1c01dda074406f38058785a69526734"},{"fixed":"da55f570191d5d72f10c607a7043b947eb05ea46"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68391.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.0.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.148"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68391.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
