| Subject: CVE-2024-36006: mlxsw: spectrum_acl_tcam: Fix incorrect list API usage |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| mlxsw: spectrum_acl_tcam: Fix incorrect list API usage |
| |
| Both the function that migrates all the chunks within a region and the |
| function that migrates all the entries within a chunk call |
| list_first_entry() on the respective lists without checking that the |
| lists are not empty. This is incorrect usage of the API, which leads to |
| the following warning [1]. |
| |
| Fix by returning if the lists are empty as there is nothing to migrate |
| in this case. |
| |

| 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: |
