| Subject: CVE-2024-46685: pinctrl: single: fix potential NULL dereference in pcs_get_function() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| pinctrl: single: fix potential NULL dereference in pcs_get_function() |
| |
| pinmux_generic_get_function() can return NULL and the pointer 'function' |
| was dereferenced without checking against NULL. Add checking of pointer |
| 'function' in pcs_get_function(). |
| |
| Found by code review. |
| |
| The Linux kernel CVE team has assigned CVE-2024-46685 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: |
