Bug Description

fs/pnode.c in the Linux kernel before 4.5.4 does not properly traverse a mount propagation tree in a certain case involving a slave mount, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted series of mount system calls.

Break-Fix: f2ebb3a921c1ca1e2ddd9242e95a1989a50c4c68 5ec0811d30378ae104f250bfc9b3640242d81e3f
