| Subject: CVE-2024-53077: rpcrdma: Always release the rpcrdma_device's xa_array |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| rpcrdma: Always release the rpcrdma_device's xa_array |
| |
| Dai pointed out that the xa_init_flags() in rpcrdma_add_one() needs |
| to have a matching xa_destroy() in rpcrdma_remove_one() to release |
| underlying memory that the xarray might have accrued during |
| operation. |
| |
| The Linux kernel CVE team has assigned CVE-2024-53077 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: |
| https://git.kernel.org/stable/c/36b7f5a4f300d038270324640ff7c1399245159d |
