| bfad_im_module_exit(); |
| fc_release_transport(bfad_im_scsi_transport_template); |
| --> Trigger double release |
| |
| Don't call bfad_im_module_exit() if bfad_im_module_init() failed. |

| 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: |
