  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\naccel/ivpu: Fix signed integer truncation in IPC receive\nFix potential buffer overflow where firmware-supplied data_size is cast\nto signed int before being used in min_t(). Large unsigned values\n(>= 0x80000000) become negative, causing unsigned wraparound and\noversized memcpy operations that can overflow the stack buffer.\nChange min_t(int, ...) to min() as both values are unsigned and can be\nhandled by min() without explicit cast.", "A flaw was found in the Linux kernel's accel/ivpu component. A local attacker could exploit a signed integer truncation vulnerability in the Inter-Process Communication (IPC) receive path. This flaw occurs when a firmware-supplied data size is incorrectly converted, leading to an oversized memory copy operation that can overflow a kernel stack buffer. Successful exploitation could result in a denial of service through a kernel crash and potentially lead to privilege escalation." ],
