| Subject: CVE-2024-46820: drm/amdgpu/vcn: remove irq disabling in vcn 5 suspend |
| |
| 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(). |
| |
| The Linux kernel CVE team has assigned CVE-2024-46820 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
| https://git.kernel.org/stable/c/aa92264ba6fd4fb570002f69762634221316e7ae |
