CVE-2021-3966

usb device bluetooth class includes a buffer overflow related to implementation of net_buf_add_mem.

CVE-2022-0553

CVE-2022-1041

In Zephyr bluetooth mesh core stack, an out-of-bound write vulnerability can be triggered during provisioning.

CVE-2022-1042

In Zephyr bluetooth mesh core stack, an out-of-bound write vulnerability can be triggered during provisioning.

CVE-2022-1841

In subsys/net/ip/tcp.c , function tcp_flags , when the incoming parameter flags is ECN or CWR , the buf will out-of-bounds write a byte zero.

CVE-2022-2741

The denial-of-service can be triggered by transmitting a carefully crafted CAN frame on the same CAN network as the vulnerable node. The frame must have a CAN ID matching an installed filter in the vulnerable node (this can easily be guessed based on CAN traffic analyses). The frame must contain th...

CVE-2022-2993

There is an error in the condition of the last if-statement in the function smp_check_keys. It was rejecting current keys if all requirements were unmet.

CVE-2022-3806

CVE-2023-0397

A malicious / defect bluetooth controller can cause a Denial of Service due to unchecked input in le_read_buffer_size_complete.

CVE-2023-0779

At the most basic level, an invalid pointer can be input that crashes the device, but with more knowledge of the device’s memory layout, further exploitation is possible.

CVE-2023-1901

The bluetooth HCI host layer logic not clearing a global reference to a semaphore after synchronously sending HCI commands may allow a malicious HCI Controller to cause the use of a dangling reference in the host layer, leading to a crash (DoS) or potential RCE on the Host layer.

CVE-2023-1902

The bluetooth HCI host layer logic not clearing a global reference to a state pointer after handling connection events may allow a malicious HCI Controller to cause the use of a dangling reference in the host layer, leading to a crash (DoS) or potential RCE on the Host layer.
