In the Linux kernel, the following vulnerability has been resolved:
accel/ivpu: Fix signed integer truncation in IPC receive
Fix potential buffer overflow where firmware-supplied data_size is cast
to signed int before being used in min_t(). Large unsigned values
(>= 0x80000000) become negative, causing unsigned wraparound and
oversized memcpy operations that can overflow the stack buffer.
Change min_t(int, ...) to min() as both values are unsigned and can be
handled by min() without explicit cast.
