Details

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.
