The SJA1000 CAN controller driver backend automatically attempt to recover from a bus-off event when built with CONFIG_CAN_AUTO_BUS_OFF_RECOVERY=y. This results in calling k_sleep() in IRQ context, causing a fatal exception.

Potential buffer overflow vulnerability in the Zephyr CAN bus subsystem

Two potential signed to unsigned conversion errors and buffer overflow vulnerabilities at the following locations in the Zephyr IPM drivers.

Potential off-by-one buffer overflow vulnerability in the Zephyr fuse file system.

Potential buffer overflow vulnerabilities n the Zephyr Bluetooth subsystem.

Two potential buffer overflow vulnerabilities at the following locations in the Zephyr eS-WiFi driver source code.

In Bluetooth mesh implementation If provisionee has a public key that is sent OOB then during provisioning it can be sent back and will be accepted by provisionee.

Potential buffer overflow vulnerabilities in the following locations: https://github.com/zephyrproject-rtos/zephyr/blob/main/drivers/usb/device/usb_dc_native_posix.c#L359 https://github.com/zephyrproject-rtos/zephyr/blob/main/drivers/usb/device/usb_...

Union variant confusion allows any malicious BT controller to execute arbitrary code on the Zephyr host.

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 po...
