CVE-2014-8559 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.74% chance of exploitation in the next 30 days.
