| Subject: CVE-2024-49871: Input: adp5589-keys - fix NULL pointer dereference |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| Input: adp5589-keys - fix NULL pointer dereference |
| |
| We register a devm action to call adp5589_clear_config() and then pass |
| the i2c client as argument so that we can call i2c_get_clientdata() in |
| order to get our device object. However, i2c_set_clientdata() is only |
| being set at the end of the probe function which means that we'll get a |
| NULL pointer dereference in case the probe function fails early. |
| |
| The Linux kernel CVE team has assigned CVE-2024-49871 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: |
