Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Execution of system commands without calling Wait leaves zombie processes, leading to host PID resource exhaustion and denial of service. Developers must ensure all spawned processes are properly reaped.
Information Disclosure: Sensitive credentials and secrets present in gRPC requests and responses were printed in plain text to logs via klog. Developers must enforce protosanitizer on all logged gRPC structures.
Denial of Service: Concurrent reads and writes to error backoff tracking maps without proper mutex synchronization caused runtime panics, exposing the CSI controller to local denial of service.
