Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to a race condition error in the HDMA controller register. The Linked list element and pointer are not stored in the same memory as the HDMA controller register. If the doorbell register is toggled before the full write of the linked list, a race condition error will occur. In remote setup, a readl to the memory can assure the full write has occurred. This issue may allow an attacker to elevate privileges in the system.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
