| Subject: CVE-2025-37811: usb: chipidea: ci_hdrc_imx: fix usbmisc handling |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| usb: chipidea: ci_hdrc_imx: fix usbmisc handling |
| |
| usbmisc is an optional device property so it is totally valid for the |
| corresponding data->usbmisc_data to have a NULL value. |
| |
| Check that before dereferencing the pointer. |
| |
| Found by Linux Verification Center (linuxtesting.org) with Svace static |
| analysis tool. |
| |
| The Linux kernel CVE team has assigned CVE-2025-37811 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: |
