Description
In the Linux kernel, the following vulnerability has been resolved:
spi: core: Abort active target transfer on controller suspend
When an SPI controller operating in target mode has a transfer in
progress at the time of system suspend, the suspend path proceeds
without aborting the ongoing transfer. This can leave the hardware in
an inconsistent state, potentially causing the system to hang or fail
to resume cleanly.
Fix this by invoking the controller's target_abort callback from
spi_controller_suspend() when the controller is in target mode and the
callback is registered. This ensures any active target transfer is
cleanly terminated before the controller is suspended.
