CVE-2026-63974

CVE-2026-63974 affects the Linux kernel Bluetooth subsystem. The issue arises in hci_sync where HCI_CMD_DRAIN_WORKQUEUE must be set during device close because hci_dev_close_sync() can be invoked on a reset path, preventing timeouts from being queued while the hdev workqueue drains. The consequen...
