**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to the fsl-qdma component of the Linux kernel, where unaligned read transactions initiated by QDMA may stall in the Network On-Chip (NOC), causing a deadlock condition. This can lead to completion timeouts in the PCIe controller. The problem is associated with chip errata, specifically the ls1028a chip. There is no information provided about the estimated number of potentially affected devices or real-world incidents where this issue was exploited. **Recommendations** To resolve the issue, enable prefetch by setting the source descriptor prefetchable bit (SD[PF] = 1) as a workaround. Implement this workaround to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
