Description

A flaw was found in the igorplugusb component of the Linux kernel. The USB request structure, when handled by Direct Memory Access (DMA) on certain host controllers, did not properly follow DMA coherency rules. This oversight could lead to data integrity issues or unexpected system behavior, as the data might not be consistent across different memory views.
