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...

CVE-2026-68392

Summary: CVE-2026-68392 affects the Linux kernel Bluetooth management path. The vulnerability arises from dereferencing RCU-protected pointers outside critical sections during unpair_device/disconnect_sync, enabling a Use-After-Free (UAF) scenario. The fix targets the critical section handling fo...

CVE-2026-68391

CVE-2026-68391 affects the Linux kernel Bluetooth management path, specifically the mgmt_pending_cmds handling of hci_conn references. The issue is a Use-After-Free risk from dereferencing RCU-protected pointers outside critical sections and from using hci_conn in hci_sync callbacks without holdi...
