Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Resource leaks in the speculative decoding engine's draft token workspace manager fail to release slots upon request completion, leading to eventual capacity exhaustion and engine-wide denial of service.
Denial of Service: A segmentation fault occurs when the engine attempts to process tokenizers missing their mandatory tokenizer.json file, allowing malformed models to crash the service.
Denial of Service: An integer overflow can trigger during memory footprint estimation when sequence length calculations with sliding windows enabled overflow native integer boundaries.
