1661503: CVE-2018-16885 kernel: out-of-bound read in memcpy_fromiovecend()
A flaw was found in the Linux kernel that allows the userspace to call memcpy_fromiovecend() and similar functions with a zero offset and buffer length. This can cause a read beyond the buffer boundaries flaw and, in certain cases, cause a memory access fault and a system halt by accessing invalid memory address.
