CVE-2017-6345

Description

The LLC subsystem in the Linux kernel before 4.9.13 does not ensure that a certain destructor exists in required circumstances, which allows local users to cause a denial of service (BUG_ON) or possibly have unspecified other impact via crafted system calls.

From the Ubuntu Security Team

Andrey Konovalov discovered that the LLC subsytem in the Linux kernel did not properly set up a destructor in certain situations. A local attacker could use this to cause a denial of service (system crash).
