| Subject: CVE-2024-43842: wifi: rtw89: Fix array index mistake in rtw89_sta_info_get_iter() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: rtw89: Fix array index mistake in rtw89_sta_info_get_iter() |
| |
| In rtw89_sta_info_get_iter() 'status->he_gi' is compared to array size. |
| But then 'rate->he_gi' is used as array index instead of 'status->he_gi'. |
| This can lead to go beyond array boundaries in case of 'rate->he_gi' is |
| not equal to 'status->he_gi' and is bigger than array size. Looks like |
| "copy-paste" mistake. |
| |
| Fix this mistake by replacing 'rate->he_gi' with 'status->he_gi'. |
| |
| Found by Linux Verification Center (linuxtesting.org) with SVACE. |
| |
| The Linux kernel CVE team has assigned CVE-2024-43842 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: |
