Memory corruption while parsing the memory map info in IOCTL calls.

Memory corruption can occur when process-specific maps are added to the global list. If a map is removed from the global list while another thread is using it for a process-specific task, issues may arise.

Transient DOS can occur when the driver parses the per STA profile IE and tries to access the EXTN element ID without checking the IE length.

Information disclosure while processing IOCTL call made for releasing a trusted VM process release or opening a channel without initializing the process.

Memory corruption while invoking redundant release command to release one buffer from user space as race condition can occur in kernel space between buffer release and buffer access.

Memory corruption while Configuring the SMR/S2CR register in Bypass mode.

Memory corruption when multiple threads try to unregister the CVP buffer at the same time.

Memory corruption when allocating and accessing an entry in an SMEM partition continuously.

Memory corruption when invalid input is passed to invoke GPU Headroom API call.

Information disclosure as NPU firmware can send invalid IPC message to NPU driver as the driver doesn`t validate the IPC message received from the firmware.
