| Subject: CVE-2024-56747: scsi: qedi: Fix a possible memory leak in qedi_alloc_and_init_sb() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| scsi: qedi: Fix a possible memory leak in qedi_alloc_and_init_sb() |
| |
| Hook "qedi_ops->common->sb_init = qed_sb_init" does not release the DMA |
| memory sb_virt when it fails. Add dma_free_coherent() to free it. This |
| is the same way as qedr_alloc_mem_sb() and qede_alloc_mem_sb(). |
| |
| The Linux kernel CVE team has assigned CVE-2024-56747 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: |
