Under undisclosed traffic conditions along with conditions beyond the attackers control, hardware systems with a High-Speed Bridge (HSB) may experience a lockup of the HSB.
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
Weakness
The product does not properly acquire or release a lock on a resource, leading to unexpected resource state changes and behaviors.

Extended Description
Locking is a type of synchronization behavior that ensures that multiple independently-operating processes or threads do not interfere with each other when accessing the same resource. All processes/threads are expected to follow the same steps for locking. If these steps are not followed precisely - or if no locking is done at all - then another process/thread could modify the shared resource in a way that is not visible or predictable to the original process. This can lead to data or memory corruption, denial of service, etc.
