CVE-2026-93169

Description

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.
