Dell PowerScale OneFS, versions 9.8.0.0 through 9.10.1.0, contain a time-of-check time-of-use (TOCTOU) race condition vulnerability. An unauthenticated attacker with local access could potentially exploit this vulnerability, leading to denial of service and information tampering.
The product checks the state of a resource before using that resource, but the resource’s state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state.
