Vulnerability Title
Rocq Prover before 9.2.0 Guard Checker Accepts Fixpoint Passed as a Higher-Order Argument
Vulnerability Description
The guard checker in Rocq Prover does not follow recursive calls made through a fixpoint's own arguments. A fixpoint may pass itself as a higher-order argument to a second fixpoint, which then applies it to a value that is not a subterm of the structural argument. Passing the recursive function to a plain definition is rejected because the checker unfolds the definition and observes the call, but passing it to a fixpoint is accepted because higher-order recursive calls through fixpoint arguments are not tracked. This admits a type that is definitionally equal to its own negation, so self-application produces False in purely definitional code, without tactics, axioms, plugins or unsafe flags, and Print Assumptions reports the result as closed under the global context. Fixed in Rocq 9.2.0.

Vulnerability Title
Rocq Prover 处理逻辑错误漏洞
Vulnerability Description
Rocq Prover是Rocq Prover组织的一个形式化证明辅助软件。 Rocq Prover 9.2.0之前版本存在处理逻辑错误漏洞,该漏洞源于guard checker未跟踪通过fixpoint自身参数进行的高阶递归调用,可能导致类型定义性等价于其自身否定,从而在纯定义性代码中产生False。
