Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Custom serializers and message serialization components (such as GraphBinaryMessageSerializerV4) are prone to memory leaks because Netty pooled ByteBuf instances are not released when exceptions (unchecked or IOExceptions) are thrown during processing.
Denial of Service: Inadequate management of HTTP transaction executor threads during commit or rollback operations can cause thread pool exhaustion, leading to a complete denial of service for incoming server requests.
Denial of Service: Unbounded maps used for caching query plans can be exploited to consume host memory progressively, leading to OutOfMemoryError crashes unless bounded by eviction policies.
