What it is

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.
