Summary
[none]
Details

The doumount function in fs/namespace.c in the Linux kernel through 3.17 does not require the CAPSYSADMIN capability for doremountsb calls that change the root filesystem to read-only, which allows local users to cause a denial of service (loss of writability) by making certain unshare system calls, clearing the / MNTLOCKED flag, and making an MNT_FORCE umount system call.
