Description

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/vcn: remove irq disabling in vcn 5 suspend We do not directly enable/disable VCN IRQ in vcn 5.0.0. And we do not handle the IRQ state as well. So the calls to disable IRQ and set state are removed. This effectively gets rid of the warining of "WARN_ON(!amdgpu_irq_enabled(adev, src, type))" in amdgpu_irq_put().

Affected products

Linux kernel: from 6.10 before 6.10.9 — fixed in 6.10.9

How to fix

Upgrade to a fixed version: Linux kernel 6.10.9. Check the vendor advisory for mitigations.
