| Subject: CVE-2024-27416: Bluetooth: hci_event: Fix handling of HCI_EV_IO_CAPA_REQUEST |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| Bluetooth: hci_event: Fix handling of HCI_EV_IO_CAPA_REQUEST |
| |
| If we received HCI_EV_IO_CAPA_REQUEST while |
| HCI_OP_READ_REMOTE_EXT_FEATURES is yet to be responded assume the remote |
| does support SSP since otherwise this event shouldn't be generated. |
| |
| The Linux kernel CVE team has assigned CVE-2024-27416 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: |
