## Technical details

A missing bounds check in NeuroPilot allows out-of-bounds write operations that could lead to local privilege escalation. The vulnerability requires the attacker to already possess system privilege; no user interaction is needed. While the exact component and attack preconditions are unclear from the advisory, the out-of-bounds write could potentially corrupt memory to bypass security controls or escalate privileges.
