| Subject: CVE-2024-35928: drm/amd/amdgpu: Fix potential ioremap() memory leaks in amdgpu_device_init() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/amd/amdgpu: Fix potential ioremap() memory leaks in amdgpu_device_init() |
| |
| This ensures that the memory mapped by ioremap for adev->rmmio, is |
| properly handled in amdgpu_device_init(). If the function exits early |
| due to an error, the memory is unmapped. If the function completes |
| successfully, the memory remains mapped. |
| |
| Reported by smatch: |
| drivers/gpu/drm/amd/amdgpu/amdgpu_device.c:4337 amdgpu_device_init() warn: 'adev->rmmio' from ioremap() not released on lines: 4035,4045,4051,4058,4068,4337 |
| |
| The Linux kernel CVE team has assigned CVE-2024-35928 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: |
