check\n\nimm_buf->len is a user-controlled uint32_t received from the network.\nAdding it to imm_data_offset without overflow checking allows a\nmalicious initiator to send len=0xFFFFFFFF, causing req_size to wrap\naround to a small value, bypassing the bounds check, and subsequently\npassing a ~4GB length to sg_init_one().\n\nUse check_add_overflow() to detect wrapping before the comparison.","state":0,"publishedAt":"2026-08-15T05:59:07.144+00:00","modifiedAt":"2026-10-16T19:05:40.869+00:00","affected":[{"ecosystem":"Vendor
