CVE-2026-46091

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...

EUVD-2026-32474

In the Linux kernel, the following vulnerability has been resolved: media: rc: igorplugusb: heed coherency rules In a control request, the USB request structure can be subject to DMA on some HCs. Hence it must obey the rules for DMA coherency. Allocate it separately...
