| Subject: CVE-2022-48788: nvme-rdma: fix possible use-after-free in transport error_recovery work |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| nvme-rdma: fix possible use-after-free in transport error_recovery work |
| |
| While nvme_rdma_submit_async_event_work is checking the ctrl and queue |
| state before preparing the AER command and scheduling io_work, in order |
| to fully prevent a race where this check is not reliable the error |
| recovery work must flush async_event_work before continuing to destroy |
| the admin queue after setting the ctrl state to RESETTING such that |
| there is no race .submit_async_event and the error recovery handler |
| itself changing the ctrl state. |
| |
| The Linux kernel CVE team has assigned CVE-2022-48788 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: |
