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.
Analysis
Linux kernel drm/imagination driver deadlock in soft reset sequence allows local denial of service when the soft reset handler calls disable_irq() from within a threaded IRQ handler context, creating a self-deadlock condition. The fix replaces disable_irq() with disable_irq_nosync() to prevent the handler from waiting on itself. …
