| Subject: CVE-2024-53203: usb: typec: fix potential array underflow in ucsi_ccg_sync_control() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| usb: typec: fix potential array underflow in ucsi_ccg_sync_control() |
| |
| The "command" variable can be controlled by the user via debugfs. The |
| worry is that if con_index is zero then "&uc->ucsi->connector[con_index |
| - 1]" would be an array underflow. |
| |
| The Linux kernel CVE team has assigned CVE-2024-53203 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: |
