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

Description A race condition error can occur in the Linux kernel due to the Linked list element and pointer not being stored in the same memory as the eDMA controller register. If the doorbell register is toggled before the full write of the linked list, this error will occur. In remote setup, a readl to the memory can assure the full write has occurred.

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