# Unknown component: base.c use-after-free race lets local users escalate privilege

A race condition in several functions of base.c can free memory that is still in use, a use-after-free. A local user with no extra privileges can use it to gain higher privileges.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

In multiple functions of base.c, there is a possible use-after-free due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
