| Subject: CVE-2022-49618: pinctrl: aspeed: Fix potential NULL dereference in aspeed_pinmux_set_mux() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| pinctrl: aspeed: Fix potential NULL dereference in aspeed_pinmux_set_mux() |
| |
| pdesc could be null but still dereference pdesc->name and it will lead to |
| a null pointer access. So we move a null check before dereference. |
| |
| The Linux kernel CVE team has assigned CVE-2022-49618 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: |
