Description
The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.
The weakness exists in the cryptographic hardware accelerator driver the affected devices have a limited amount of Direct Memory Access (DMA) memory and the affected software improperly handles resources in low-memory conditions. A remote attacker can send a sustained, high rate of malicious traffic to an affected device, exhaust DMA memory and cause the device to reload and result in a temporary DoS condition.
