CVE-2024-26790

MEDIUM
Published Apr 4, 2024 Modified Feb 27, 2025 CWE-667

Description

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.
