| Subject: CVE-2023-53118: scsi: core: Fix a procfs host directory removal regression |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| scsi: core: Fix a procfs host directory removal regression |
| |
| scsi_proc_hostdir_rm() decreases a reference counter and hence must only be |
| called once per host that is removed. This change does not require a |
| scsi_add_host_with_dma() change since scsi_add_host_with_dma() will return |
| 0 (success) if scsi_proc_host_add() is called. |
| |
| The Linux kernel CVE team has assigned CVE-2023-53118 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: |
