| Subject: CVE-2024-57980: media: uvcvideo: Fix double free in error path |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| media: uvcvideo: Fix double free in error path |
| |
| If the uvc_status_init() function fails to allocate the int_urb, it will |
| free the dev->status pointer but doesn't reset the pointer to NULL. This |
| results in the kfree() call in uvc_status_cleanup() trying to |
| double-free the memory. Fix it by resetting the dev->status pointer to |
| NULL after freeing it. |

| 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: |
