| Subject: CVE-2022-49491: drm/rockchip: vop: fix possible null-ptr-deref in vop_bind() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/rockchip: vop: fix possible null-ptr-deref in vop_bind() |
| |
| It will cause null-ptr-deref in resource_size(), if platform_get_resource() |
| returns NULL, move calling resource_size() after devm_ioremap_resource() that |
| will check 'res' to avoid null-ptr-deref. |
| |
| The Linux kernel CVE team has assigned CVE-2022-49491 to this issue. |

| ========== |
| |
| 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: |
