## Technical details

A double free vulnerability occurs in the NPU driver due to improper pointer management, where a memory region is freed more than once. This can lead to heap corruption and may allow an attacker with local access to trigger a denial of service or potentially achieve code execution, depending on heap implementation details and exploit complexity.
