Upgrade zephyrproject-rtos/zephyr to version 4.4.1-rc1 or higher.
Overview
Affected versions of this package are vulnerable to Out-of-bounds Write in the nrf_wifi_event_proc_get_power_save_info process. An attacker can cause memory corruption and potentially execute arbitrary code or crash the system by triggering the processing of a malformed or out-of-range event from the co-processor firmware, which results in writing past the bounds of a fixed-size array on the stack. This is only exploitable if the system is built with CONFIG_NRF70_STA_MODE enabled and the co-processor firmware emits an event with an excessive TWT flow count.
