| Subject: CVE-2023-52515: RDMA/srp: Do not call scsi_done() from srp_abort() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| RDMA/srp: Do not call scsi_done() from srp_abort() |
| |
| After scmd_eh_abort_handler() has called the SCSI LLD eh_abort_handler |
| callback, it performs one of the following actions: |
| * Call scsi_queue_insert(). |
| * Call scsi_finish_command(). |
| * Call scsi_eh_scmd_add(). |
| Hence, SCSI abort handlers must not call scsi_done(). Otherwise all |
| the above actions would trigger a use-after-free. Hence remove the |
| scsi_done() call from srp_abort(). Keep the srp_free_req() call |
| before returning SUCCESS because we may not see the command again if |
| SUCCESS is returned. |
| |
| The Linux kernel CVE team has assigned CVE-2023-52515 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: |
