CVE-2026-68393

The CVE-2026-68393 entry concerns the Linux kernel Bluetooth hci_sync component. The root cause is the use of RCU-protected pointers outside their critical sections without proper reference counting, which could lead to a Use-After-Free (UAF). The fix extends the critical section to cover both th...
