| Subject: CVE-2023-52507: nfc: nci: assert requested protocol is valid |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| nfc: nci: assert requested protocol is valid |
| |
| The protocol is used in a bit mask to determine if the protocol is |
| supported. Assert the provided protocol is less than the maximum |
| defined so it doesn't potentially perform a shift-out-of-bounds and |
| provide a clearer error for undefined protocols vs unsupported ones. |
| |
| The Linux kernel CVE team has assigned CVE-2023-52507 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: |
