Description OSIDB Bzimport 2025-09-15 15:03:55 UTC 
In the Linux kernel, the following vulnerability has been resolved:

spi: imx: Don't skip cleanup in remove's error path

Returning early in a platform driver's remove callback is wrong. In this
case the dma resources are not released in the error path. this is never
retried later and so this is a permanent leak. To fix this, only skip
hardware disabling if waking the device fails.
