Major Security Threats
Memory-Related Vulnerabilities
- Buffer Overflow: Allows attackers to cause memory corruption through cross-memory space operations
- Memory Leakage: Uninitialized memory access and failure to clear memory after release leads to sensitive data leakage
- Return Address Overwrite: Allows attackers to modify return addresses stored in local memory
AI-Specific Attacks
- Model Theft: Attackers can exploit GPU memory vulnerabilities to steal AI models
- Inference Manipulation: Through carefully crafted malicious requests, exploiting buffer overflow vulnerabilities in GPU kernels
- DNN Application Attacks: Targeting DNN-based applications causing significant security risks
Virtualization Environment Threats
- GPU Side-Channel Attacks: Information leakage between virtual GPUs
- Resource Contention Attacks: Malicious exploitation of GPU resource scheduling mechanisms
Defense Mechanisms and Strategies
Memory Security Mechanisms
- Address Space Layout Randomization (ASLR): Increases attack difficulty, but implementation on GPUs may have defects
- Non-Executable Memory (NX bit): Prevents direct execution of injected code, but support is incomplete
- Canary Values: Detects buffer overflows, identifying attack attempts early
Secure Programming Practices
- Avoiding functions that don't perform boundary checks
- Using compilers that help identify unsafe operations
- Rearranging memory layout to reduce vulnerability risks
System-Level Defenses
