CVE-2014-8559

Priority
Description
The d_walk function in fs/dcache.c in the Linux kernel through 3.17.2 does
not properly maintain the semantics of rename_lock, which allows local
users to cause a denial of service (deadlock and system hang) via a crafted
application.
Ubuntu-Description
A flaw was discovered with file renaming in the linux kernel. A local user
could exploit this flaw to cause a denial of service (deadlock and system
hang).
Notes
jdstrandandroid kernels (flo, goldfish, grouper, maguro, mako and manta) are
not supported on the Ubuntu Touch 14.04 preview kernels
linux-lts-saucy no longer receives official support
linux-lts-quantal no longer receives official support
"See vfs.git#experimental-d_walk - the first commit there moves
d_rcu from d_child to d_alias, the second is basically "skip the killed
siblings rather than restarting the tree walk"
