| Subject: CVE-2023-52694: drm/bridge: tpd12s015: Drop buggy __exit annotation for remove function |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/bridge: tpd12s015: Drop buggy __exit annotation for remove function |
| |
| With tpd12s015_remove() marked with __exit this function is discarded |
| when the driver is compiled as a built-in. The result is that when the |
| driver unbinds there is no cleanup done which results in resource |
| leakage or worse. |
| |
| The Linux kernel CVE team has assigned CVE-2023-52694 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: |
