| Subject: CVE-2023-53017: Bluetooth: hci_sync: fix memory leak in hci_update_adv_data() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| Bluetooth: hci_sync: fix memory leak in hci_update_adv_data() |
| |
| When hci_cmd_sync_queue() failed in hci_update_adv_data(), inst_ptr is |
| not freed, which will cause memory leak, convert to use ERR_PTR/PTR_ERR |
| to pass the instance to callback so no memory needs to be allocated. |
| |
| The Linux kernel CVE team has assigned CVE-2023-53017 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/8ac6043bd3e5b58d30f50737aedc2e58e8087ad5 |
