| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| Input: i8042 - fix leaking of platform device on module removal |
| |
| Avoid resetting the module-wide i8042_platform_device pointer in |
| i8042_probe() or i8042_remove(), so that the device can be properly |
| destroyed by i8042_exit() on module unload. |
| |
| The Linux kernel CVE team has assigned CVE-2022-49777 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: |
