| Subject: CVE-2024-35937: wifi: cfg80211: check A-MSDU format more carefully |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: cfg80211: check A-MSDU format more carefully |
| |
| If it looks like there's another subframe in the A-MSDU |
| but the header isn't fully there, we can end up reading |
| data out of bounds, only to discard later. Make this a |
| bit more careful and check if the subframe header can |
| even be present. |
| |
| The Linux kernel CVE team has assigned CVE-2024-35937 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: |
