| Subject: CVE-2024-35838: wifi: mac80211: fix potential sta-link leak |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: mac80211: fix potential sta-link leak |
| |
| When a station is allocated, links are added but not |
| set to valid yet (e.g. during connection to an AP MLD), |
| we might remove the station without ever marking links |
| valid, and leak them. Fix that. |
| |
| The Linux kernel CVE team has assigned CVE-2024-35838 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: |
