Vulnerability from github – Published: 2026-04-03 18:31 – Updated: 2026-05-26 15:32

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.

Severity

5.5 (Medium)


                  
                    CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
