Last modified

CVE-2016-6213 is a vulnerability of currently unknown severity. fs/namespace.c in the Linux kernel before 4.9 does not restrict how many mounts may exist in a mount namespace, which allows local users to cause a denial of service (memory consumption and deadlock) via MS_BIND mount system calls, as demonstrated by a loop that triggers exponential growth in the number of mounts.. EPSS estimates a 0.37% chance of exploitation in the next 30 days.
