CVE-2016-4581

Priority
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.
Ubuntu-Description
It was discovered that in some situations the Linux kernel did not handle
propagated mounts correctly. A local unprivileged attacker could use this
to cause a denial of service (system crash).
Notes
jdstrandandroid kernels (flo, goldfish, grouper, maguro, mako and manta) are
not supported on the Ubuntu Touch 14.10 and earlier preview kernels
linux-lts-saucy no longer receives official support
linux-lts-quantal no longer receives official support
