Description

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.

Affected configurations

• linux linux kernel (>= 6.8 < 6.12.94) • linux linux kernel (>= 6.13 < 6.18.36) • linux linux kernel (>= 6.19 < 7.0.13) • linux linux kernel 7.1
