Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: dmaengine: fsl-qdma: fix SoC may hang on 16 byte unaligned read There is chip (ls1028a) errata: The SoC may hang on 16 byte unaligned read transactions by QDMA. Unaligned read transactions initiated by QDMA may stall in the NOC (Network On-Chip), causing a deadlock condition. Stalled transactions will trigger completion timeouts in PCIe controller. Workaround: Enable prefetch by setting the source descriptor prefetchable bit ( SD[PF] = 1 ). Implement this workaround.
