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.
