| Subject: CVE-2024-43883: usb: vhci-hcd: Do not drop references before new references are gained |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| usb: vhci-hcd: Do not drop references before new references are gained |
| |
| At a few places the driver carries stale pointers |
| to references that can still be used. Make sure that does not happen. |
| This strictly speaking closes ZDI-CAN-22273, though there may be |
| similar races in the driver. |
| |
| The Linux kernel CVE team has assigned CVE-2024-43883 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: |
