# Unnamed product: input validation flaw allows local denial of service

Multiple code locations in an unnamed product do not validate input properly, so malformed input can crash or stall the software. The sources say an attacker needs local user-level execution and no user interaction is required.

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

## From the sources

In multiple locations, there is a possible denial of service due to improper input validation. This could lead to local denial of service with User execution privileges needed. User interaction is not needed for exploitation.
