Description

PingCAP TiDB v8.1.0 was discovered to contain a buffer overflow via the component expression.ExplainExpressionList.

NOTE: PingCAP maintains that the actual reproduction of this issue did not cause the security impact of service interruption to other users. They argue that this is a complex query bug and not a DoS vulnerability.
