| Subject: CVE-2024-26889: Bluetooth: hci_core: Fix possible buffer overflow |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| Bluetooth: hci_core: Fix possible buffer overflow |
| |
| struct hci_dev_info has a fixed size name[8] field so in the event that |
| hdev->name is bigger than that strcpy would attempt to write past its |
| size, so this fixes this problem by switching to use strscpy. |
| |
| The Linux kernel CVE team has assigned CVE-2024-26889 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: |
