CVE-2026-68392Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: mgmt: fix locking in unpair_device/disconnect_sync Dereferencing RCU-protected pointers outside critical sections is invalid and may lead to UAF. Take hdev->lock for hci_conn lookup and hci_abort_conn(). Don't use RCU to ensure the conn is fully initialized at this point. A flaw was found in the Linux kernel's Bluetooth management subsystem. This vulnerability occurs due to incorrect locking when handling memory pointers during device unpairing and disconnection. An attacker could exploit this to trigger a Use-After-Free (UAF) condition, which is a type of memory corruption that may lead to system instability or other impacts. Systems without Bluetooth are not affected. Red Hat severity: Moderate — CVSS 5.5…
