Executive Summary

This vulnerability is a memory leak in the Linux kernel's habanalabs accelerator driver. It occurs when user memory mappings are captured and then cleared improperly if a new context is opened immediately after capturing user mappings and a hard reset is performed. This causes allocated memory to not be freed correctly.

Impact Analysis

The memory leak can lead to increased memory usage over time, potentially causing system instability or degraded performance due to exhaustion of available memory resources.
