CVE-2018-16885
Last modified
CVE-2018-16885 is a medium-severity vulnerability rated 4.7/10 on the CVSS scale. 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 which causes the read beyond the buffer boundaries, in certain cases causing a memory access fault and a system halt by accessing invalid memory address. This issue only affects kernel version 3.10.x as shipped with Red Hat Enterprise Linux 7.. EPSS estimates a 0.42% chance of exploitation in the next 30 days.
