CVE-2026-31773 Bluetooth: SMP: derive legacy responder STK authentication from MITM state

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: SMP: derive legacy responder STK authentication from MITM state The legacy responder path in smprandom currently labels the stored STK as authenticated whenever pendingseclevel is BTSECURITYHIGH. That reflects what the...

CVE-2026-31773

The CVE-2026-31773 entry concerns the Linux kernel Bluetooth SMP implementation. The root cause is that the legacy responder path in smp_random() marks the STK as authenticated whenever pending_sec_level is BT_SECURITY_HIGH, which reflects the requested security level rather than the actual pairi...

CVE-2026-31771

CVE-2026-31771 affects the Linux kernel Bluetooth HCI event handling. The vulnerability arose because hci_store_wake_reason() could be invoked before per-event payload length checks, potentially allowing a short HCI event frame to reach bacpy() prior to validation. The fix restructures wake-addre...
