Symantec Endpoint Encryption prior to SEE 11.2.1 MP1 may be susceptible to a Privilege Escalation vulnerability, which is a type of issue whereby an attacker may attempt to compromise the software application to gain elevated access to resources that are normally protected from an application or user.

In Symantec Endpoint Encryption before SEE 11.1.3HF3, a kernel memory leak is a type of resource leak that can occur when a computer program incorrectly manages memory allocations in such a way that memory which is no longer needed is not released. In object-oriented programming, a memory leak may happen when an object is stored in memory but cannot be accessed by the running code.
