spi dma

About this tag
The tag 'spi dma' covers a specific Linux kernel vulnerability (CVE-2026-31560) affecting the DesignWare SPI DMA path. The flaw involves a crash caused by faulty error logging: when a DMA transaction times out or encounters an error, the driver may dereference a missing SPI message while printing the error log. This issue highlights that crashes can originate from error-handling code rather than the failed hardware transaction itself. The NVD record was published in April 2026 and remains awaiting enrichment, so administrators should treat scanner severity labels as provisional. The tag is relevant for Linux system administrators, kernel developers, and security professionals dealing with SPI DMA stability and kernel error handling.

  1. CVE-2026-31560: Linux SPI DMA Crash Caused by Faulty Error Logging

    CVE-2026-31560 is a small Linux kernel fix with an outsized lesson: sometimes the crash is not in the failed hardware transaction, but in the error log that tries to describe it. The flaw sits in the DesignWare SPI DMA path, where a timeout or error could leave the driver without a current SPI...
