| Subject: CVE-2023-52595: wifi: rt2x00: restart beacon queue when hardware reset |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: rt2x00: restart beacon queue when hardware reset |
| |
| When a hardware reset is triggered, all registers are reset, so all |
| queues are forced to stop in hardware interface. However, mac80211 |
| will not automatically stop the queue. If we don't manually stop the |
| beacon queue, the queue will be deadlocked and unable to start again. |
| This patch fixes the issue where Apple devices cannot connect to the |
| AP after calling ieee80211_restart_hw(). |
| |
| The Linux kernel CVE team has assigned CVE-2023-52595 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: |
