CVE-2026-23470 PUBLISHED

drm/imagination: Fix deadlock in soft reset sequence

Assigner: Linux
Reserved: 13.01.2026 Published: 03.04.2026 Updated: 03.04.2026

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.
