Memory corruption via virtual-memory stack buffer overflow
Published Oct 9, 2025 · Updated Oct 9, 2025
A stack-based buffer overflow in Qualcomm Snapdragon Auto chipsets allows local users to corrupt memory through virtual-memory control commands. The virtual memory management interface overflows a stack buffer while processing control commands, but Qualcomm does not disclose the affected function or unchecked operation. The path requires local low-privilege access and no user interaction; successful triggering corrupts memory, while the public record identifies no demonstrated crash or code-execution outcome.
