Description OSIDB Bzimport 2026-04-24 15:05:07 UTC

In the Linux kernel, the following vulnerability has been resolved:

spi: spi-dw-dma: fix print error log when wait finish transaction

If an error occurs, the device may not have a current message. In this
case, the system will crash.

In this case, it's better to use dev from the struct ctlr (struct spi_controller*).
