| Subject: CVE-2024-42276: nvme-pci: add missing condition check for existence of mapped data |

| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |

| |
| nvme_map_data() is called when request has physical segments, hence |
| the nvme_unmap_data() should have same condition to avoid dereference. |
| |

| 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: |
