Large unsigned values\n(>= 0x80000000) become negative, causing unsigned wraparound and\noversized memcpy operations that can overflow the stack buffer.\n\nChange min_t(int, ...) to min() as both

cast.","state":0,"publishedAt":"2026-06-25T08:39:10.287+00:00","modifiedAt":"2026-10-19T19:57:28.409+00:00","affected":[{"ecosystem":"Vendor
