Title:CVE-2015-8539 on Ubuntu 18.04 LTS (bionic) - medium.
Description:The KEYS subsystem in the Linux kernel before 4.4 allows local users to gain privileges or cause a denial of service (BUG) via crafted keyctl commands that negatively instantiate a key, related to security/keys/encrypted-keys/encrypted.c, security/keys/trusted.c, and security/keys/user_defined.c. 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.
