| Subject: CVE-2024-43847: wifi: ath12k: fix invalid memory access while processing fragmented packets |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: ath12k: fix invalid memory access while processing fragmented packets |
| |
| The monitor ring and the reo reinject ring share the same ring mask index. |
| When the driver receives an interrupt for the reo reinject ring, the |
| monitor ring is also processed, leading to invalid memory access. Since |
| monitor support is not yet enabled in ath12k, the ring mask for the monitor |
| ring should be removed. |
| |
| Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.1.1-00209-QCAHKSWPL_SILICONZ-1 |
| |
| The Linux kernel CVE team has assigned CVE-2024-43847 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/8126f82dab7bd8b2e04799342b19fff0a1fd8575 |
