| Subject: CVE-2024-44961: drm/amdgpu: Forward soft recovery errors to userspace |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/amdgpu: Forward soft recovery errors to userspace |
| |
| As we discussed before[1], soft recovery should be |
| forwarded to userspace, or we can get into a really |
| bad state where apps will keep submitting hanging |
| command buffers cascading us to a hard reset. |

| 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/0da0b06165d83a8ecbb6582d9d5a135f9d38a52a |
