NVD

In the Linux kernel, the following vulnerability has been resolved:

drm/imagination: Fix deadlock in soft reset sequence

The soft reset sequence is currently executed from the threaded IRQ handler, hence it cannot call disable irq() which internally waits for IRQ handlers, i.e. itself, to complete.

Use disable irq nosync() during a soft reset instead.
