Description OSIDB Bzimport 2026-09-17 17:18:52 UTC 
In the Linux kernel, the following vulnerability has been resolved:

dmaengine: zynqmp_dma: fix race between runtime PM and device removal

In zynqmp_dma_remove(), runtime PM was disabled only after checking
state and doing a manual suspend. This can race with runtime PM in the
remove/unbind (rmmod) path.

Disable runtime PM first, then suspend only if the device is not already
suspended. To prevent any further runtime PM transitions.
