| Subject: CVE-2023-52809: scsi: libfc: Fix potential NULL pointer dereference in fc_lport_ptp_setup() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| scsi: libfc: Fix potential NULL pointer dereference in fc_lport_ptp_setup() |
| |
| fc_lport_ptp_setup() did not check the return value of fc_rport_create() |
| which can return NULL and would cause a NULL pointer dereference. Address |
| this issue by checking return value of fc_rport_create() and log error |
| message on fc_rport_create() failed. |
| |
| The Linux kernel CVE team has assigned CVE-2023-52809 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: |
