Description OSIDB Bzimport 2026-05-27 15:10:21 UTC 
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.
