| Subject: CVE-2024-36951: drm/amdkfd: range check cp bad op exception interrupts |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/amdkfd: range check cp bad op exception interrupts |
| |
| Due to a CP interrupt bug, bad packet garbage exception codes are raised. |
| Do a range check so that the debugger and runtime do not receive garbage |
| codes. |
| Update the user api to guard exception code type checking as well. |
| |
| The Linux kernel CVE team has assigned CVE-2024-36951 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: |
