Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
spi: microchip-core-qspi: don&#39;t attempt to transmit during emulated read-only dual/quad operations<br />
<br />
The core will deal with reads by creating clock cycles itself, there&#39;s<br />
no need to generate clock cycles by transmitting garbage data at the<br />
driver level. Further, transmitting garbage data just bricks the transfer<br />
since QSPI doesn&#39;t have a dedicated master-out line like MOSI in regular<br />
SPI. I&#39;m not entirely sure if the transfer is bricked because of the<br />
garbage data being transmitted on the bus or because the core loses<br />
track of whether it is supposed to be sending or receiving data.
