| 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. 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).
