CVE-2026-68392
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: mgmt: fix locking in unpairdevice/disconnectsync Dereferencing RCU-protected pointers outside critical sections is invalid and may lead to UAF. Take hdev-lock for hciconn lookup and hciabortconn. Don't use RCU to ensur...
CVE-2026-68390
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: hold hdev-lock for hciconnparams lookups hciconnparamslookup requires hdev-lock be held, otherwise the list iteration or param access is not safe. Hold hdev-lock for params lookups in hcisync...
CVE-2026-68393
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: extend connhash lookup critical sections Using RCU-protected pointers outside the critical sections without refcount is incorrect and may result to UAF. Extend critical section to cover both hciconnhash lookup...
CVE-2026-68394
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: MGMT: revalidate LOADCONNPARAM queued update MGMTOPLOADCONNPARAM queues connupdatesync when a single parameter update changes an existing LE central connection. The queued work currently stores a borrowed hciconnparams...
CVE-2026-68391
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: mgmt: hold reference for hciconn in mgmtpendingcmds Dereferencing RCU-protected pointers outside critical sections is invalid and may lead to UAF. Use of hciconn in hcisync callbacks also needs to hold refcount to avoi...
