| Subject: CVE-2023-52661: drm/tegra: rgb: Fix missing clk_put() in the error handling paths of tegra_dc_rgb_probe() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/tegra: rgb: Fix missing clk_put() in the error handling paths of tegra_dc_rgb_probe() |
| |
| If clk_get_sys(..., "pll_d2_out0") fails, the clk_get_sys() call must be |
| undone. |
| |
| Add the missing clk_put and a new 'put_pll_d_out0' label in the error |
| handling path, and use it. |
| |
| The Linux kernel CVE team has assigned CVE-2023-52661 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: |
