Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，已修复以下漏洞： spi: 核心层：在控制器挂起时中止正在进行的主动目标传输 当 SPI 控制器以目标模式运行，且在系统挂起时仍有传输正在进行时，挂起流程会继续执行，而不会中止正在进行的传输。这可能导致硬件处于不一致状态，进而引发系统挂起或无法正常恢复的问题。 修复方法：在 spi_controller_suspend() 函数中，当控制器处于目标模式且已注册 target_abort 回调时，调用该回调函数。此举可确保在控制器挂起之前，干净地终止任何正在进行的主动目标传输。

Vulnerability Title
spi: core: Abort active target transfer on controller suspend
Source: CVE Program / CVE List V5
Vulnerability 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.
