| Subject: CVE-2024-47718: wifi: rtw88: always wait for both firmware loading attempts |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: rtw88: always wait for both firmware loading attempts |
| |
| In 'rtw_wait_firmware_completion()', always wait for both (regular and |
| wowlan) firmware loading attempts. Otherwise if 'rtw_usb_intf_init()' |
| has failed in 'rtw_usb_probe()', 'rtw_usb_disconnect()' may issue |
| 'ieee80211_free_hw()' when one of 'rtw_load_firmware_cb()' (usually |
| the wowlan one) is still in progress, causing UAF detected by KASAN. |
| |
| The Linux kernel CVE team has assigned CVE-2024-47718 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: |
