CVE-2026-80764

CVE-2026-80764 affects the Linux kernel Bluetooth subsystem. The vulnerability is a use-after-free (UAF) in the HCI event handler: hci_cc_reset() clears the LE accept and resolving lists without acquiring hdev->lock , while debugfs readers (e.g., white_list_show) hold that lock while traversin...

EUVD-2026-71406

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcievent: validate LE Set CIG Parameters response The Command Complete dispatch validates only the fixed part of the LE Set CIG Parameters response. After that part is pulled from the skb, hcicclesetcigparams trusts...

CVE-2026-80763

CVE-2026-80763 is an out-of-bounds read in the Linux kernel Bluetooth HCI subsystem. In hci_cc_le_set_cig_params(), the handler trusts the num_handles field of the LE Set CIG Parameters Command Complete response and reads the trailing handle array without verifying that the remaining skb data act...

CVE-2026-80762

CVE-2026-80762 is a use-after-free in the Linux kernel Bluetooth HCI subsystem (hci_sync). The function hci_update_event_filter_sync() walks the device's accept list while issuing synchronous HCI commands per remote-wakeup device. The suspend path holds hdev->req_lock, but accept-list mutation...

CVE-2026-80760

CVE-2026-80760 affects the Linux kernel Bluetooth MGMT subsystem. The function mgmt_hci_cmd_sync() validates that the message length matches params_len but fails to enforce an upper bound. Since params_len is a 16-bit value while the HCI command header plen field is 8-bit (max 255), a value of 25...

kernel: Bluetooth: hci_ldisc: Clear HCI_UART_PROTO_INIT on error

A flaw was found in the Linux kernel's Bluetooth Host Controller Interface HCI Universal Asynchronous Receiver/Transmitter UART driver. When the hciregisterdev function fails, a flag indicating protocol initialization is not properly cleared. This oversight allows incoming UART data to be process...
