| Subject: CVE-2024-57997: wifi: wcn36xx: fix channel survey memory allocation size |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: wcn36xx: fix channel survey memory allocation size |
| |
| KASAN reported a memory allocation issue in wcn->chan_survey |
| due to incorrect size calculation. |
| This commit uses kcalloc to allocate memory for wcn->chan_survey, |
| ensuring proper initialization and preventing the use of uninitialized |
| values when there are no frames on the channel. |
| |
| The Linux kernel CVE team has assigned CVE-2024-57997 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: |
