| Subject: CVE-2024-53240: xen/netfront: fix crash when removing device |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| xen/netfront: fix crash when removing device |
| |
| When removing a netfront device directly after a suspend/resume cycle |
| it might happen that the queues have not been setup again, causing a |
| crash during the attempt to stop the queues another time. |
| |
| Fix that by checking the queues are existing before trying to stop |
| them. |
| |
| This is XSA-465 / CVE-2024-53240. |
| |
| The Linux kernel CVE team has assigned CVE-2024-53240 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: |
