| Subject: CVE-2022-49046: i2c: dev: check return value when calling dev_set_name() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| i2c: dev: check return value when calling dev_set_name() |
| |
| If dev_set_name() fails, the dev_name() is null, check the return |
| value of dev_set_name() to avoid the null-ptr-deref. |
| |
| The Linux kernel CVE team has assigned CVE-2022-49046 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: |
