| Subject: CVE-2022-49713: usb: dwc2: Fix memory leak in dwc2_hcd_init |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| usb: dwc2: Fix memory leak in dwc2_hcd_init |
| |
| usb_create_hcd will alloc memory for hcd, and we should |
| call usb_put_hcd to free it when platform_get_resource() |
| fails to prevent memory leak. |
| goto error2 label instead error1 to fix this. |
| |
| The Linux kernel CVE team has assigned CVE-2022-49713 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: |
