| Subject: CVE-2024-38562: wifi: nl80211: Avoid address calculations via out of bounds array indexing |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: nl80211: Avoid address calculations via out of bounds array indexing |
| |
| Before request->channels[] can be used, request->n_channels must be set. |
| Additionally, address calculations for memory after the "channels" array |
| need to be calculated from the allocation base ("request") rather than |
| via the first "out of bounds" index of "channels", otherwise run-time |
| bounds checking will throw a warning. |
| |
| The Linux kernel CVE team has assigned CVE-2024-38562 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: |
