Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
s390/vfio_ccw: Ensure first IDAW remains constant<br />
<br />
The first IDAW in a list does not need to be on a 2K/4K boundary<br />
like all others, and so is read separately to accurately calculate<br />
the size of the buffer needed to read the full IDAL.<br />
<br />
Verify that the address found in the first IDAW is unchanged between<br />
reads, to ensure a consistent set of IDAWs being worked with.
