| Subject: CVE-2025-37986: usb: typec: class: Invalidate USB device pointers on partner unregistration |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| usb: typec: class: Invalidate USB device pointers on partner unregistration |
| |
| To avoid using invalid USB device pointers after a Type-C partner |
| disconnects, this patch clears the pointers upon partner unregistration. |
| This ensures a clean state for future connections. |
| |
| The Linux kernel CVE team has assigned CVE-2025-37986 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: |
