| Subject: CVE-2024-58059: media: uvcvideo: Fix deadlock during uvc_probe |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| media: uvcvideo: Fix deadlock during uvc_probe |
| |
| If uvc_probe() fails, it can end up calling uvc_status_unregister() before |
| uvc_status_init() is called. |
| |
| Fix this by checking if dev->status is NULL or not in |
| uvc_status_unregister(). |
| |
| The Linux kernel CVE team has assigned CVE-2024-58059 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: |
| https://git.kernel.org/stable/c/db577ededf3a18b39567fc1a6209f12a0c4a3c52 |
