Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Improper handling of PyObject reference counts during RESP3 map parsing allows an external data source or malicious Redis server to cause memory leaks of parsed keys, values, and intermediate tuples, leading to system memory exhaustion.
Denial of Service: Failure to release custom error callback references (protocolErrorClass and replyErrorClass) during Reader object deallocation causes a memory leak over the application lifetime when Reader objects are repeatedly created and destroyed.
