| Subject: CVE-2024-42289: scsi: qla2xxx: During vport delete send async logout explicitly |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| scsi: qla2xxx: During vport delete send async logout explicitly |
| |
| During vport delete, it is observed that during unload we hit a crash |
| because of stale entries in outstanding command array. For all these stale |
| I/O entries, eh_abort was issued and aborted (fast_fail_io = 2009h) but |
| I/Os could not complete while vport delete is in process of deleting. |
| |
| BUG: kernel NULL pointer dereference, address: 000000000000001c |
| #PF: supervisor read access in kernel mode |
| #PF: error_code(0x0000) - not-present page |

| 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: |
