Upgrade zephyrproject-rtos/zephyr to version 4.4.1-rc1 or higher.
Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference in the transfer-completion handlers of the MAX32 USB device controller driver due to dereferencing a buffer pointer without verifying it is not NULL. An attacker can cause the device to crash by sending a new SETUP packet to abort an in-flight EP0 control transfer, resulting in a stale transfer-completion event being processed against an empty FIFO and triggering a near-NULL pointer dereference.
