Summary
In the Imagination DRM driver in the Linux kernel, a deadlock occurs during soft reset because disable_irq() is called from the IRQ handler context, causing a self-wait.
Risk Assessment
The deadlock can cause system hangs or graphics driver crashes, affecting system stability.
Recommendation
Apply the Linux kernel patch that uses disable_irq_nosync() instead of disable_irq().
Original NVD description (English source)
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.
