CVE-2015-8539 [HIGH] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Dmitry Vyukov discovered that the key management subsystem in the Linux
kernel did not properly restrict adding a key that already exists but is
negatively instantiated. A local attacker could use this to cause a denial
of service (system crash) or possibly execute arbitrary code.
