| Subject: CVE-2023-52777: wifi: ath11k: fix gtk offload status event locking |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: ath11k: fix gtk offload status event locking |
| |
| The ath11k active pdevs are protected by RCU but the gtk offload status |
| event handling code calling ath11k_mac_get_arvif_by_vdev_id() was not |
| marked as a read-side critical section. |
| |
| Mark the code in question as an RCU read-side critical section to avoid |
| any potential use-after-free issues. |
| |
| Compile tested only. |
| |
| The Linux kernel CVE team has assigned CVE-2023-52777 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: |
